Introduction

Congratulations on the purchase of your Art Morrison Enterprises GT Sport chassis. This frame is the result of

many years of chassis and suspension design experience. In an effort to make your project progress smoothly,

we have compiled this booklet containing instructions, notes and tips on removal of your current frame as well

as assembly and installation of your new GT Sport chassis.

Art Morrison Enterprises’ Engineering department has

chosen C6/7 knuckles for their superior strength, design

and aftermarket support. Simply using C6/7 parts,

however, will not guarantee the best performance.

Countless hours were spent utilizing computer modeling

and analysis to ensure the suspension provided on this

frame provides excellent performance yet fits the

packaging necessary on A-bodies.

The GT Sport frames follow the Art Morrison design

philosophy that combines simplicity and elegance. We believe stiffening material and bracing should only be

added as necessary because too much only leads to additional weight. High stiffness can be obtained by

geometric design rather than adding material.

The 1968-72 GT Sport chassis uses a fully boxed mid-rail section with strategically placed bracing that connects

to a 2x3 underfloor structure. The cross bracing has the option to bolt to the body’s stiffening ribs if desired.

Unlike stock frames, this frame makes use of 3/16” wall front 2x4 rails to combat a common weakness in A-

Bodies – front frame sag.

Body Mounting

The Art Morrison GT Sport chassis is a bolt-on frame, meaning it bolts to the body as the original frame did.

Please refer to a Fisher Body Manual for removal and assembly instructions.

The 1968-72 GT Sport chassis is designed to use AME’s aluminum body mount kit. This kit ensures the frame is

mounted as close as possible to the frame. While OEM-spec body mounts may be used, some mounts will

require shimming and the body will sit ½” higher.

Because of the zero compressibility of aluminum mounts, consider running medium strength thread locker on

the body bolts.

Engine Fitment Your new GT Sport frame will accept small block, big block and LS-series Chevrolet engines. The engine frame

mounts are a multi-position design to move big block engines forward to clear the firewall, while all others move

the engine as far back as possible to optimize weight balance. Stock frame configuration offsets engines to the

passenger side which makes room for steering boxes and power brake boosters; however since a steering box is

no longer utilized the engine has been centered within the vehicle. This may require the use of a smaller power

brake booster or an alternative method of power brake assistance. For proper fitment LS engines require the

use of adapter plates available only from Art Morrison Enterprises; the utilization of adapter plates from other

manufacturers may generate clearance issues. LS F-Body engine accessories (including A/C compressors) will

typically fit within the frame rails. Corvette, GTO, CTS and truck accessory configurations will also fit. When

shopping for an aftermarket drive system, pay particular attention to the area left of the engine oil pan as this is

where the steering rack will reside.

The engine oil pan design is critical for proper performance as well as trouble-free installation. Due to the

steering rack location, oil pans typically will need to have a minimum front depth. For small and big blocks,

traditional front pan depths (similar to stock) will be adequate. For LS engines, choose a pan that is similar to a

98-02 F-Body or LS2 oil pan. For reference, front pan depths should be around 1-7/8”.

Transmission Fitment

The GT Sport frame is designed to support modern manual and automatic transmissions. Manual transmissions

will require the use of a hydraulic throwout bearing as Z-bars are not supported.

Due to the size of modern transmissions, there is a possibility of requiring the transmission tunnel to be

modified. In general, transmissions requiring tunnel modification on stock chassis cars will be the same with a

GT Sport frame as engine mount locations are very similar.

If using a new transmission that does not yet have aftermarket support, a custom crossmember may be

required.

Steering Column & Linkage To use the stock steering column a rag joint adapter must be attached onto the column end to accommodate a

universal joint. Due to this process, some stock steering columns may have an interference problem between

the universal joint and the frame rail and can be solved by using an aftermarket column that is shorter in length.

An aftermarket steering column should be utilized for several reasons. First, the column can be ordered in any

length for maximum flexibility. Second, the welcome addition of a tilt feature and all new components as well

as zero steering shaft radial play, makes these columns a convenient choice. Third, they feature a 1” double-D

end for easy linkage hook-up. Lastly, most manufacturers offer steering columns that are 2” diameter which

allows you to reuse the factory firewall mount and optional dash mounts for a true bolt-in installation. An AME

steering linkage kit provides you with all the necessary parts to connect an aftermarket column to the steering

rack is available from Art Morrison Enterprises.

Brake Lines Art Morrison Enterprises offers a brake line kit to make this task easy and includes all necessary fittings and

clamps to provide fluid to the brake calipers. Due to the variety of braking systems, a short line will need to be

fabricated from the master cylinder (or combination valve) to the front line kit. All line kits are made from 304

stainless steel and feature -03AN fittings with all stainless hardware.

Wheels & Tires While the GT Sport’s hub track is similar to stock, there are other considerations to examine before using wheels

for a stock chassis. First, the brakes used on a GT Sport chassis requires close attention regarding overall

diameter and caliper offset. Second, the chassis will lower the car much more than stock and typically will

require slightly more positive offset. While Art Morrison Enterprises has gone to great lengths to ensure proper

wheel and tire fitment, variations can occur from vehicle assembly or modifications/repairs over the years that

affect fitment. Backspacing and proper fitment should be double checked before ordering wheels!

The distance between inner rear tire to inner rear tire must be 47-1/4” or greater if minitubs are not used. Most

cars must not have an outer bulge width greater than 72” if the fender lips are not trimmed, and no more than

72-1/2” if the fender is trimmed. We recommend a maximum of 295mm rear tires without minitubs assuming

the frame is precisely centered in the body. If the car is minitubbed, a maximum rear tire width of 335mm is

recommended.

Up front, a 275mm tire can be used with steering stops. Depending on the diameter of the tire and final ride

height, some inner front fender modifications may be required.

Buick/Olds/Pontiacs may have wider front and rear fenders. Please double check measurements with these cars

to ensure the wheels are ordered correctly the first time.

Axle Housings When ordering a GT Sport frame, several axle housing options are available. To make selection simple the

housing width can be specified to replicate stock, 3” narrow, or a custom width.

All axle housings are a modern rendition of a Ford 9” design. These housings include a brand new stamped

center section (Fab 9 is optional), 3” diameter 3/16” wall axle tubes, and forged tube ends. All housings are built

on a precise fixture that ensures proper wheel alignment.

Frame Fit and OEM Tolerances Art Morrison Enterprises has done extensive testing to ensure the frame matches OEM specifications while

maintaining much tighter tolerances than GM’s specifications as produced over 45 years ago.

Over the years, these vehicles have been subjected to high miles, accidents, racing and lastly, time. Many of

these vehicles have been in accidents but the damage from which is no longer readily evident, however these

incidents may have severely distorted the location of body mounts. Even low mileage, pristine “survivor cars”

can suffer from body sag due to uneven spring settling. Due to these factors, the body mounts located on the

frame may be slightly different than those on the body shell. This is considered normal, and is often not an issue

thanks to a large amount of adjustability. When fitting the frame to the body, shimming the body mounts is

recommended if a precise fit is desired.

El Camino and Wagon frames are 4” longer in the mid-section between which equates to a wheelbase of 116”

(from 112”) and a 6” longer rear overhang (distance between rear axle centerline and rear of frame). Four-door

models share the same 116” wheelbase, but do not have a 6” longer rear overhang. All BOP models share the

same dimensions as the Chevelle.

Frame & Component Installation & Setup Frame removal and installation follow identical procedures between the stock frame and GT Sport frame. Refer

to the factory shop manuals for procedures and torque settings.

Prior to assembling the frame to body, all brake lines, fuel lines, parking brake cables, etc. should be attached.

To prevent interference later, it is imperative to be mindful of where the engine and headers will sit.

Prior to finishing, the frame should be disassembled. As the frame is assembled at Art Morrison Enterprises the

front and rear suspension is pre-set to initial alignment specifications as a quality check. To maintain these

settings, prior to getting the car aligned, be sure to take measurements of upper control arm shims and tie rod

lengths.

Ideally, all welding and drilling should be completed prior to powdercoating or painting. Please note that all

welds must not be ground smooth as this will weaken the frame’s structural integrity. If you wish to have the

welds smoothed use body filler instead.

After the finishing operation has been completed the frame can now be assembled. Set the frame on a level

surface in a well-lit area. Next, use a rat-tail file to clean all holes which bolts pass through and make sure all

threaded bosses are clear of powder or paint. To finish the preparation process, collect all fasteners and have

the torque specifications sheet handy.

To begin assembling, install the upper control arm/knuckle/lower control arm assembly by first fastening the

lower control arm bolts to the frame. Next, bolt the upper control arm to the frame ensuring that the alignment

bushings lay between the two. Hand-tighten all fasteners for now and repeat the process on the opposite side.

Now, install the steering rack with the fasteners, hand-tighten and attach the tie rod end to the knuckle. To

install the sway bar, first attach the end linkage to the bar using the drawing as a guide. Then attach the linkage

to the control arm and rotate the bar toward the bottom of the frame for attachment. To mount the coilovers,

attach the lower mount to the control arm with the provided fasteners and then attach the upper mount to the

chassis. As a starting point, set the coil spring adjuster to 1” above the lowest adjustment point.

When plumbing the steering rack, note the fitting closest to the radiator is the pressure line and the other is the

return. To start the bleeding process, first fill the reservoir full of power steering fluid. With the reservoir cap

removed and the wheels off the ground, turn the steering wheel lock-to-lock twenty times while monitoring the

fluid level. When complete, the engine can be started and checked for leaks. Before driving for the first time,

rotate the steering wheel another four times. See the Steering Rack Technical Guide later in this manual for

other important information.

To complete the assembly process attach any brake lines, brackets, transmission crossmember and other

necessary components. Check every fastener for proper torque and mark with a paint pen as a visual

indicator.

If you purchased the optional Wilwood brake kit it is imperative the break-in procedure be followed very

carefully. Failure to follow these directions will lead to glazed pads and poor braking performance. If these

directions are missing from your brake kit, visit www.wilwood.com to download their instructions.

Post-Drive Checklist After the first 100 miles, please check these items:

1. All fasteners (including wheel lugs) 2. Brake fluid (Fluid level and check fittings for leaks) 3. Power steering fluid (Fluid level and check fittings for leaks) 4. Coolant (Fluid level and check fittings for leaks)) 5. Transmission fluid (if applicable) 6. Fuel lines (Check fittings for leaks) 7. Brake Lines (Check fittings for leaks) 8. Battery cables 9. Exhaust system

The coil springs should also be checked and readjusted if necessary. New springs will typically settle once after

several miles and usually do not need a second adjustment.

Important: Lifting a Vehicle with Two-Post Lifts The debate of choosing a four or two post lift is something that many can have strong opinions about.

While driving the vehicle onto a four post lift is convenient, it comes at a cost of requiring another

lifting assembly to raise the vehicle off of the ramps in order to remove the wheels and perform any

brake or suspension work.

Two post lifts solve this problem by lifting the vehicle by the frame or reinforced unibody structures.

However, the problem will arise with a two-post in which the vehicle is lifted unnaturally, meaning

loads are placed in areas that will cause some beaming flex. This type of flex is a function of frame

stiffness and body stiffness, with the frame stiffness is typically 30-40% of the total beaming stiffness.

Vehicles with heavy drivetrains will increase flex, as the majority of this weight (engines and axle

housings) are far away from the lifting points.

It should be noted that this flex is completely normal. Dealerships and OEMs use two posts lift which

should be a testament to their safety. However, this issue can become a problem with vehicles with

precision door gaps that are tighter than typical OEM specifications or body panels that have been

modified or removed for larger engines, aesthetics, etc. Panels and doors should always be fitted with

the vehicle on the ground or the frame properly supported in some way. Convertibles will always see

much more flex than coupes and sedans, to the point that doors may not open or shut. In most cases,

the older the vehicle, the higher probability for flex as body stiffness increased with newer vehicle

designs with more stringent safety standards.

While beaming flex may be alarming to some people, this does not mean the vehicle won’t drive

correctly. As mentioned before, it’s simply loading the vehicle in an unnatural way. Vehicles are

meant to be driven with the normal road force applied to the vehicle’s suspension, not applied to the

area below the rocker panels. Loading the vehicle properly allows the forces to be efficiently

transmitted through bracing and body panels with the upper areas in compression, whereas loading at

the rocker loads these areas in tension with the drivetrain and suspension acting as ballast which

encourages flex.

In summary, beaming flex is a normal occurrence when using two post lifts. Vehicles of all types, new

or old, full frame or unibody, coupes/sedans and convertibles, will flex. The magnitude of this flex

depends on vehicle age, condition, construction, design, drivetrain weight, and lastly the lifting point

spread – all of which is to be expected.

Brake Clearance Due to the Corvette knuckle and hub assembly, precautions MUST be taken to ensure the wheel will clear the brake caliper. Unlike older brake systems, the outside face of the caliper is 1.27” past the wheel mount surface. If using aftermarket brakes, please follow the manufacturer’s recommendation for proper clearance.

Steering Rack Technical Information

Hoses

For those using -06AN hoses, AME can supply the proper fittings. Be aware that some aftermarket

fittings do not use the correct threads and can damage the casting. Before installing, coat the O-ring

with power steering fluid and torque the fitting to 20 lb-ft.

The return hose can be any type of low-pressure hydraulic hose. The pressure hose can exhibit

pressures above 1500PSI and requires a high pressure hose. We do not recommend the use of any

stainless steel braided/Teflon lined hose for its inability to dampen hydraulic “chatter”, thus creating a

growl sound when turning the steering wheel. To keep this noise to a minimum, use a hose with a

rubber length of 15” or more.

The pressure fitting on the rack casting is the fitting closest to the front of the vehicle (lower fitting),

and the return fitting is the closest to the firewall (upper fitting).

Rack Centering

It is easier to center the steering rack before mounting the unit to the chassis. To center the rack, turn

the pinion to full lock and measure between any point on the rack body to the end of the tie rod in the

extended direction. Divide this distance by two, and rotate the pinion in the opposite direction until

this distance is reached. The rack is now centered. Using a paint pen, mark the pinion’s location on

the seal or housing so the rack can be re-centered if moved later.

Mounting

All Mustang-type steering racks mount using 5/8”-NF x 3.5” bolts when using an Art Morrison chassis.

Be sure to liberally coat the threads with anti-seize before installing. Torque bolts to 50 lb-ft. When

using rebuilt steering racks, end boots may be loosened and rotated to move the 3/16” equalizer tube

to a different location if more clearance is needed.

Tuning

Both steering racks respond well to fluid flow rates between 2 to 3 gallons per minute. Less flow tends

to increase steering effort, but too little may lead to pump “catch” where power steering assist

momentarily stops until the pump can “catch up” to the required fluid flow. Too much flow may lead

to a steering feel that is too light and possibly twitchy. Some power steering pumps have adjustable

flow rates, while most OEM type pumps do not. If you feel the fluid flow rate may be too high, contact

Art Morrison Enterprises for a valve that will allow approximately 2 gallons per minute of fluid flow.

14

ART MORRISON ENTERPRISES, INC 5301 8TH STREET EAST FIFE, WASHINGTON, 98424 (800) 929-7188 www.artmorrison.com (253) 922-7188 FAX (253) 922-8847

Keep in mind that pumps originally used for steering boxes typically have higher pressure and flow

rates than what is required for steering racks.

If your pump provides too much pressure, fluid may escape past seals in the steering rack and cause a

failure, particularly with rebuilt steering racks. Art Morrison Enterprises has a pressure reducing kit to

correct these situations.

For cars using wide tires, Art Morrison Enterprises can supply steering stops that snap on to the rack

shaft with the boots removed. This provides a simple way to limit steering travel for cars with

interference issues.

Bleeding Procedure (Important! Do not skip this procedure!)

1. Place the front end of the vehicle on jack stands and remove drive belt. 2. Fill reservoir with high quality power steering fluid and rotate the pump pulley by hand for

about thirty seconds. 3. Have a second person rotate the steering wheel from lock to lock, about thirty times, while

continuing to rotate the power steering pump pulley by hand. Watch the fluid reservoir to make sure it does not run dry.

4. Install the drive belt and start the engine. Continue to rotate the steering wheel from lock to lock about fifteen times while the engine idles. Watch the fluid reservoir to make sure it does not run out of fluid, or appear foamy. If foam does appear, shut off the engine and restart the bleeding process.

5. When fluid appears free of foam, top off the reservoir and check for leaks.

This lengthy bleeding process will ensure the majority of the air is removed before initial startup to

prevent pump damage and provide trouble-free steering.

This guide is specific for a C6 suspension using the new steering arm, which is most likely to have wide

tires and wheels installed. However, for Pro Spindle based suspensions, the results are similar. To

install the limiter, roll the rubber boot away from the rack body and snap the plastic clip into place.

*Note: This angle represents the outside wheel when in a turn. The forward edge of the inside wheel

moves away from the frame and suspension, which negates any contact problem. When Ackerman is

considered, the actual maximum steering angle is 33 degrees.

Fastener Information & Torque Specifications

AME is now offering an upgraded line of fasteners to

come standard with every AME chassis to provide

you with OEM quality grade fasteners for your street

machine or race car. AME’s chassis fasteners utilize a

Magni Coating for increased corrosion resistance,

flanged nuts and bolts for a greater load distribution,

and distorted thread locking nuts for a larger

resistance to loosening forces.

Advantages:

Resists corrosion up to 13x’s longer than typical Zinc

plated fasteners

Magni coating meets several OEM manufacturer

specifications including GM, Ford, and Chrysler

Flanged fasteners provide a larger load distribution on

the mating surface typically eliminating washers

Distorted thread lock nuts provide the increased

resistance to loosing forces from vibration and movement

Identification:

Magni coated fasteners consist of a Zinc base coat with an Aluminum top coat which results

in a gray-silver finish

Distorted Thread locking nuts with flanges have a distinctive tapered top edge and the

locking nuts without flanged contain a hexagon impression on the side.

Instructions:

All AME chassis are assembled with the Magni coated flanged bolts, but use Zinc plated jam

nuts for ease of assembly and mock-up during the building process

The matching lock nuts are provided loose in a bag with the chassis components

Upon final assembly only replace the jam nuts with the Magni Distorted Thread Lock Nuts

Installation of these nuts requires a significant increase in effort compared to other lock nuts.

They will generate some amount of heat during installation due to the interference fit.

Avoid reinstallation as much as possible. Like nylon-lock nuts, the locking capability wears

slightly every use, therefore if the tightening effort dramatically decreases, replace the nut

Reference AME torque specifications for final torque values

Contact AME for any replacement pieces of hardware or to retro-fit your previously

purchased chassis with the upgraded fasteners
