PRECAUTIONS

Creams are available to protect the skin from a con-

dition known as occupational, or contact dermatitis. This

common type of dermatitis is not contagious. Improved

resin formulas in the approved kits have almost elimi-

nated skin irritation. Cream is supplied with the kit for

men who may have a tendency toward skin irritation

from the resins or dust.

The application of these creams is recommended

whenever the Resin Kit materials are used. Generally,

the cream is not required when the plastic solder kit is

being used. Directions for using the cream is as follows:

a. Wash hands clean. Dry thoroughly.

b.
Squeeze about 1/2 inch (or 1/2 teaspoonful) of

#71 cream into palm of hand.

c. Spread evenly and lightly until cream disappears.

Work cream into cuticle, between fingers and

around wrists.

d. Apply second coat, repeating Steps b and c.

e. Hold hands briefly under cold running water to

set cream.

2.
Remove resin mixture from hands as soon as possi-

ble and imperatively before mixture starts to gel.

This can be observed by the action of the material

being used. Resin may be removed with lacquer

thinner by washing in soap and water.

3.
Respirators are recommended when grinding. Also

some minor skin irritation from glass and powdered

cured resin may be evident. Washing in cold water

will help to minimize.

4.
Use a belt sander with a vacuum attachment for dust

control if possible.
5. Resin mixtures may produce toxic fumes and should

be used in well ventilated areas.

6. Be careful not to get any resin material on clothing.

7. Use the right materials for the job. It is important

to use the approved kits because Chevrolet's rigid

quality standards assure you the right material to

do the job. Other materials available may not meet

the required engineering and safety standards.

8. Keep the materials, utensils and work area clean

and dry. These repairs involve chemical reactions,

and dirt or moisture may upset the chemical bal-

ances and produce unsatisfactory results.

9. Before starting repair operations, look for hidden

damage by applying pressure around the damaged

area, looking for hairline cracks and other breakage.

Check for minor damage at other points in the vehi-

cle such as around exhaust pipes, grille, headlamps

and points of wear or rub. Early repair of this

minor damage may prevent major repair later.

PLASTIC SOLDER
KIT

The Plastic Solder Repair Kit is used for minor re-

pairs on the Corvette body. These materials will produce

an easy, quick and lasting repair in the case of small

cracks, surface imperfections and small holes.

1.
Use paint remover or power sander, and remove

finish from damaged area. Carefully inspect for

other areas requiring repair.

2.
Mix the materials (fig. 72).

3.
Apply the material, using a putty knife or rubber

squeegee, Figure 73. Work the material into the

repair and build the material up to the desired

GENERAL DESCRIPTION

.
The lighting system includes: the main lighting switch,

stop light, dimmer, and backing lamp switches, head-

lamps, parking lamps, stop, tail and directional lamps,

instrument illumination and indicator lamps, and the

necessary wiring to complete the various circuits. A

fuse panel provides convenient power take offs and fuse

clips for the appropriate circuits (fig. 1).

Chevrolet and Chevelle headlamp installation is all

new in that the headlamps are located in the radiator

support with adjusting screws and springs. Eliminating

the need for having separate headlamp housings. Chev-

rolet and Chevelle headlamp retainers and springs are

interchangeable.

Chevy n headlamp housings are new because of revised

front end styling and Corvette front end lighting is basi-

cally carryover.

Front fender lamps have been added as an option for

Chevrolet models and as standard equipment on Caprice

series.

Camaro models use single headlamps and the Rally

Sport model headlamps are covered by a retractable

section of the grille when lamps are not used. The sec-

tion of the grille covering the headlamps folds back when

lights are required; the headlamps are stationary. The

covering is retracted by a small electric motor mounted

to the headlamp housing. The headlamps are automat-

ically uncovered when the headlight switch is pulled "ON"

for illumination. If at any time the electrical circuit

becomes inoperative, the lamps can be uncovered manu-

ally. The ignition switch must be
"ON"
in order to close

the headlamp doors.

Parking lamp for Chevelle and Chevrolet models are
new due to revised front end sheet metal and bumper

styling. Parking lamps are located in the bumper on

Chevrolet, Chevelle and Chevy n models

Camaro parking lamps are located in the radiator

grille except for the Rally Sport models on which the

parking lamps are in the valance panel. For styling

reasons, the lens is white and an amber glass bulb is

used. All Camaro parking lamps require a separate

ground wire to assure a good ground contact because of

the plastic grille and painted contact surfaces.

The Chevrolet tail, stop, and directional lamps are in

one housing with a three section lens design on Impala

and Caprice sedans. The center lens for Impala series

is the back-up lamp. The center lens on the Caprice is

a tail lamp with the back-up lamps being located in the

rear bumper. Chevrolet station wagons have three indi-

vidual housings with three lenses, the center lamp being

the back-up. Biscayne and Bel-Air sedans have a single

housing and lens for tail, stop, and directional lamp with

a similarly constructed back-up lamp inboard and adja-

cent to it.

Chevelle tail, stop, and directional lamps are a single

lens design that follows through with the rear fender

styling. The back-up lamp is located in r.ear bumper.

Camaro models except Rally Sport have tail lamps

with integral back-up lamps mounted inboard of the rear

fenders between the trunk opening and bumper. The

Rally Sport model has dual tail lamps in the rear housing

and valance mounted back-up lamps.

Corvette, Chevy n, and Corvair tail and directional

signal lights are carryover. The Corvette has new back-

up lamps center mounted above the license plate opening.

By referring to the wiring diagrams, circuits may be

tested for continuous circuit or shorts with a conventional

test lamp or low reading volt meter.

HEADLAMP ADJUSTMENT-

T-3 HEADLAMPS

CAUTION: Check and tighten radiator support

grille retaining bolts prior to attempting head-

lamp aiming. Distorted grille or supports in

this area will hinder proper aiming of head-

lamps. On Corvette models make sure head-

lamp panel is adjusted properly - refer to

"Headlamp Panel Travel Adjustment".

When aiming headlamps, vehicle should be filled to ca-

pacity with gas, oil, and water but no load. Tires should

be uniformly inflated to recommended pressure.

the T-3 Safety Aimer-Type B (fig. 2), is used for the

headlamp aiming description that follows. An adapter is

required with the Type B T-3 Aimer when adjusting the 7

inch headlamp used on the Chevy n vehicle.

1.
Drive vehicle onto selected aiming area. Bounce

vehicle several times and allow to settle.

2.
Remove headlamp bezels.

3.
Mount the T-3 Aimers on either the No. 1 or No. 2

pair of headlamps so that "the points of the headlamps

engage the smooth inner ring of the aimers.

Repeat the above procedure on the right-hand

lamp to complete the horizontal adjustment of the

headlamps.

VERTICAL ADJUSTMENT

8. a. Numeral "2" (fig. 5) should appear in the "down"

window of each aimer. If not, loosen knob at

underside of aimer arm and slide back and forth

until the numeral does appear.

NOTE:
This setting will give a 2" drop of the

headlamp high beam spot centerline on a screen

placed 25 feet forward of the vehicle. Check

state laws for proper vertical setting.

b.
Turn headlamp vertical aim screw (fig. 5) on left-

hand unit counter-clockwise until the bubble is at

the inner end of the glass tube. Then turn screw

clockwise until bubble is centered in tube.

c. Repeat this procedure on right-hand headlamp

unit to complete vertical adjustment of lamps.

9. Recheck the string at the ends of each crossarm for

correct setting and the bubble on each aimer for

centered position.

10.
Remove the aimers by pulling on the suction cup tabs

through the openings in the aimers (fig. 6).

7- Selecting Level Aiming Area

4.
After botli bubbles are centered, turn the car around

end for end, making sure the tires are in the spots

made on the floor before the car was moved.

.5.
If the bubbles are still within the two outside black

marks on the vials, the floor is level enough to use

the Aimer as it comes from the factory.

NOTE:
A quick level check can be made by

using the T-3 Safety-Aimer as a level. Use

with a true eight to ten foot two by four as an

extension. Make sure pads on base of Aimer

are used. Place the board where you expect the

wheels to be and take readings as outlined above.

6. If either bubble moves outside the black lines of the

vial there is too much slant to the floor. Try driving

the car in at different angles onto the aiming area.

If bubbles can
not
be centered follow procedure under

"How to Compensate for Unlevel Floor."

NOTE:
When level portion of floor is obtained,

mark tire spots on floor so spots can be used

next time without calibrating Aimer.

TO COMPENSATE FOR UNLEVEL FLOORS

If your floor is not level within the limits specified, the

T-3 Aimer can be calibrated to compensate for the error

in the floor. Follow this procedure with both aimers.

1.
Drive the car onto the area for which you wish to

compensate the aimers, and install the aimers in

place on the headlamps.

2.
Loosen knob beneath the aimer arm and move the

slider until the bubble is centered.

3.
Record the numeral in the view window. (This nu-

meral is to be used only for recalibration.)

4.
Move the slider to a position halfway between this
