The folding top adjustments are:

Header (View A, Fig. 101)

Header assembly may be moved fore and aft when the

two clamping screws are loosened. This will correct such

conditions as header latch guide pin alignment with the

holes in the windshield upper frame. Symptoms of mis-

alignment are such conditions as loose top trim when

top is up and locked, and excessive effort required to

engage header locks. Note that it will be necessary to

remove side roof rail weatherstrip to gain access to

header outer clamping screw. Refer to Weatherstrip

portion of this section.

Hinge (View B, Fig. 101)

The hinges may be moved up and down and fore and aft

to the limit of the slotted holes in hinge plate and body.

To gain access to hinge, remove rigid plastic trim as

explained in Interior Trim portion of this section. Re-

positioning hinge will correct conditions such as poor top

fit at upper and rear edge of windows; faulty fore and aft

engagements of rear bow hold-down pins in lock assem-

blies and loose or oversight top rear panel when top is

raised and properly locked in position.

Rear Bow Hold-Down Locks (View C, Fig. 101)

The hold-down pins may be moved to left or right to
center top on body in raised position; thus correcting

poor alignment at windows and difficult entry of pins

in locks.

TOP ASSEMBLY REMOVAL AND INSTALLATION

The entire top assembly (frame with trim attached)

may be removed from vehicle as follows:

1.
Raise top, but do not engage header or rear bow

locks.

2.
Remove rigid plastic trim as outlined in Interior

Trim portion of this section.

3.
Mark installed position of hinge by scribing outline

of hinge plate on lock pillar surface.

4.
Remove two screws retaining each hinge to lock

pillar and remove top assembly from vehicle.

5.
When installing top assembly, carefully match hinge

plate with scribed marks on body lock pillar and

WEATHERSTRIP

Side Rail Weatherstrip

Figure 111 illustrates installation of side rail weather-

strip which acts to seal window opening. The weather-

strip is held in place by studs which are part of the

weatherstrip assembly, and by neoprene base cement

which is applied between weatherstrip and side rail

surface.

When replacing weatherstrip remove all rust, old

cement and foreign material from the surfaces to be

cemented, to assure successful bonding. Use only good

quality neoprene cement suitable for weatherstrip

application.

Header Weatherstrip

Weatherstrip assembly is retained to the header panel

by a combination of studs, sheet metal screws and special

fasteners as shown in Figure 112, along with neoprene

base weatherstrip cement.

Figure 99 shows' a cross section of weatherstrip taken

through a special fastener. To replace fastener, rotate

ninety degrees to align fastener head with slot. Follow

directions for cementing in the Side Rail Weatherstrip

instructions preceding this write up.

ADDING HARDTOP (ROOF PANEL ASSEMBLY)

An available roof panel assembly (hardtop) complete

can be added to convertible model Corvettes. The hard-

ware is included with the panel assembly.

Reworking of a plastic part (one for each side of the

roof panel) can be used as a marker for drilling of two

required holes in the folding top compartment lid* Hard-

ware is attached at four locations — two on the lid and

two (one each side) at the lock pillar area as follows:

1.
Rework two plastic retainers (#6280765) (used on

Chevrolet and Corvair door inner panels for trim

retention) as shown by Figure 113.

2.

GENERAL DESCRIPTION

CHEVROLET AND CHEVELLE

Frames used on Chevrolet and Cheveile lines are basi-

cally the same, consisting of full length right and left

side members joined laterally by crossmembers. Sev-

eral different frames are used in each line to meet the

various vehicle size and function requirements but the

basic shape for each line remains the same. Differences

between frames in a given line exist only in metal gauge,

part size and numbers of parts necessary to meet the

particular structural requirements of the models

involved.

CORVETTE

The Corvette frame is a rigid perimeter unit, with five
crossmembers. From the rear kick-up forward, trap-

azoidal shaped, closed side members outline and protect

the passenger compartment. At the cowl area, the side

members curve inward in a sweeping "S" shape, to pro-

vide a sturdy foundation for the engine mounts and clear-

ance for front wheel movement. From the kick-up

rearward, box-sectioned side rails provide fore and aft

support for the rear axle and suspension. Lateral sup-

port is provided by five variously shaped welded-in

crossmembers, including the front unit, which formerly

was bolted-in.

CHEVY II AND CAMARO

Underbody alignment checking procedures will be found

in the Body Service Manual.

REPAIR PROCEDURES

CHECKING FRAME ALIGNMENT

Vehicles involved in an accident of any nature which

might result in a "swayed" or "sprung" frame should

always be checked for proper frame alingment in addi-

tion to steering geometry and wheel alignment.

CAR PREPARATION

Preparing the car for the frame alignment check in-

volves the following:

1.
Place the car on level surface.

2.
The weight of the car should be supported at the

wheel locations.

3.
A visual damage inspection should be made to elim-

inate needless measuring. Obviously damaged or

misaligned areas can often be located by sight.

TRAMMING SEQUENCE

When checking a frame for alignment in case of dam-

age,
the first step is horizontal "X" checking with a

tram from similar given points on opposite side of the

frame.

Frame alignment checks on all models should be made

with the tram points set at the center of each locating

point indicated and the cross bar level to insure

accuracy.

When "X" checking any section of the frame, the

measurements should agree within 3/16". If they do not,
it means that corrections will have to be made.

If a tram gauge is not available, the "plumb bob"

method of checking may be used. To assure any degree

of accuracy when using this method, the vehicle should

be on a level floor.

By using this method, it is only necessary to have a
#

piece of cord attached to an ordinary surveyor's plumb

bob.
When measuring the distance between two points,

the free end of the cord should be placed on the reference

point allowing the plumb bob to hang on the floor. A check

mark should be made on the floor just under the tip of

the plumb bob. This operation should be repeated at all

reference points. With these points located on the floor,

they may easily be measured with a rule.

The second step is checking the vertical dimensions

from the datum plane to the points to be trammed. With

the proper settings the tram bar will be on a plane

parallel to that of the frame. The exception to this would '

be when one of the reference locations is included in the

misaligned area; then the parallel plane between the

frame and the tram bar may not prevail. After com-

pletion of the repairs, the tram gauge should be set at

the specified dimension to check the accuracy of the re-

pair operation.

ALIGNMENT REFERENCE POINT DIMENSIONS

Dimensions to holes are measured to dead center of

the holes and flush to the adjacent surface metal.

GENERAL DESCRIPTION

The 1967 Chevrolet, Chevelle, Camaro, Chevy n and

Corvette front suspension systems are basically similar,

being of the
S.L.A.
(short-long arm) type with independent

coil springs. In the Chevrolet, Chevelle, Camaro and

Corvette the springs ride on the lower control arms; in
the Chevy II the springs ride on the upper control arms.

Spherical joints connect the upper and lower arms to the

steering knuckle. Tapered roller wheel bearings are

used.

Camber angle is adjusted, on the Chevrolet and Chevy n

by means of a lower control arm inner pivot cam; on the

Chevelle, Camaro and Corvette by means of upper control

arm inner support shaft shims.

Caster angle is adjusted, on the Chevrolet and Chevy n

by means of a strut rod which runs from the lower con-

trol arm forward to a frame brace; on the Chevelle,
Camaro and Corvette by means of upper control arm

inner support shaft shims.

A stabilizer bar is used on all Chevelle and Corvette

models. Chevrolet Impalas, station wagons and V-8

engine equipped models are fitted with the stabilizer bar.

MAINTENANCE AND ADJUSTMENTS

Maintenance intervals recommended for lubrication of

front suspension components have been fully covered in

Section 0 of this manual. Only actual adjustment proce-

dures will be covered here.

NOTE:
Unless otherwise indicated all proce-

dures will apply to all five vehicles covered in

this manual.

FRONT WHEEL BEARING ADJUSTMENT

Proper front wheel bearing adjustment has a definite

bearing on the safe operation of a vehicle. Improperly

adjusted front wheel bearings will result in a lack of

steering stability causing wheel wander, shimmy and ex-

cessive tire wear. Very accurate adjustment is possible

because the spindles are drilled both vertically and hori-

zontally and the adjusting nuts are slotted in all six sides.

NOTE:
Wheel bearings should not
be.
repacked

or adjusted as a part of "New Car Conditioning".
1.
With wheel raised, remove hub cap and dust cap and

then remove the cotter pin from the end of the

spindle.

2.
While rotating wheel, tighten spindle nut to 12 lbs. ft

torque.

3.
Back off adjusting nut one flat and insert cotter pin.

If slot and pin hole do not line up, back off the adjust-

ing nut an additional 1/2 flat or less as required to

insert cotter pin.

4.
Spin the wheel to check that it rolls freely and then

lock the cotter pin by spreading the end and bending

it around.

NOTE:
Bearings should have zero preload and

.001"
to .008" end movement when properly ad-

justed on Chevrolet, Chevelle, Camaro and Cor-

vette; .000" to .004" on Chevy H.

5.
Install dust cap, hub cap or wheel disc and lower

wheel.

6. Perform the same operation on each front wheel.
