GENERAL DESCRIPTION

The new front end appearance of the 1967 Chevrolet

and Chevelle passenger cars affects the servicing and

replacement of the chassis sheet metal. Refer to Section

13 for Radiator and Grille service procedures, Section
14 for Bumpers, and Section 1A for Air Conditioning

components. Figures 1 and 2 illustrate the Chevrolet

and Chevelle sheet metal components.

MAINTENANCE AND ADJUSTMENTS

HOOD ADJUSTMENT

The alignment of the hood is controlled by the position

of the hood hinges and the height of the two bumpers lo-

cated one at each side of the radiator support. The ad-

justment at the hood lock must be made after the hinges

and bumpers are properly adjusted. To align the hood

and lock proceed as follows:

HOOD HINGE (Fig. 3)

NOTE:
The body mounted portion of the hood

hinges are slotted to provide up and down move-

ment. The hood mounted end is slotted to pro-

vide forward and rearward movement.

1.
Scribe a line around the entire hinge plate to be re-

positioned.
2.
Loosen the appropriate screws and shift the position

of the hood into correct alignment using the scribe

marks to check amount of movement. Check align-

ment by tightening screws and closing the hood.

HOOD BUMPERS

Adjust hood bumpers so that hood top surface is flush

with the fender and grille top surfaces. Refer to Fig-

ures 4 and 5 for correct sheet metal adjustment dimen-

sions.

HOOD CATCH AND LOCK

The hood catch assembly (fig. 6) mounting holes are

slotted to provide adjustment for the hood lock bolt. Ad-

just the hood lock bolt until hood engages securely when

closed and hood bumpers are slightly compressed.

CHEVROLET CHASSIS SERVICE MANUAL

CHASSIS SHEET METAL 11-20

GENERAL DESCRIPTION

The Camaro sheet metal components are much the

same as other Chevrolet passenger models as shown in

Figure 32. The front end design is such that servicing

of the fenders and skirts is most efficiently performed
by removing the fender and skirt as an assembly. Refer

to Section 14 for bumper service procedures, Section 13

for radiator and grille, and Section 1A for air condition-

ing components.

MAINTENANCE AND ADJUSTMENTS

HOOD ADJUSTMENT

The Camaro hood is adjusted in the conventional man-

ner, by adjustment of the hood bumpers and hinges. The

two hood bumpers are located on each side at the top of

the radiator support. Do not attempt hood latch adjust-

ments until the hinges and bumpers are correctly ad-

justed. Latch adjustments are made so that effort re-

quired to open and close the hood is reasonable, and

hood alignment obtained by hinge and bumper adjust-

ment is maintained when the hood is closed. Note that

the hood latch is not designed to correct basic hood mis-

alignment.

HOOD HINGE (Fig. 33)

NOTE: The body mounted portion of the hood

hinges are slotted to provide up and down move-

ment. The hood mounted end is slotted to pro-

vide forward and rearward movement.

1.
Scribe a. line around the entire. hinge plate to be

repositioned.

2.
Loosen the appropriate screws and shift the position

of the hood into correct alignment using the scribe

marks to check amount of movement. Check align-

ment by tightening screws and closing the hood.

HOOD BUMPERS

Adjust hood bumpers so that hood top surface is flush

with fender and header panel top surfaces. See Figure

34 for correct sheet metal adjustment dimensions.

HOOD CATCH AND LOCK (Fig. 35)

Adjust hood lock bolt so that top surface of hood is

flush with top surface'of header panel. The distance that

the lock bolt protrudes out of the lock plate should be

adjusted so that the hood bumpers are slightly com-

pressed by the fully latched hood, and effort required

to release the hood catch is reasonable. Close the hood

and insure catch engages securely.

FENDERS

Fenders are adjustable with shims at the cowl and

rocker panel. To add or remove shims, loosen bolts
Fig. 33 - Hood Hinge - Camaro

at shim locations (fig. 36) and carefully apply force with

pry bar to provide clearance for shim removal or in-

stallation.

SHEET METAL

For proper operation of doors and hood, and for pre-

sentable appearance, adjust front sheet metal to the di-

mensions shown in Figure 34.

nents on Camaro, note position and attachment

of all seals and dust shielding and replace if

necessary.
