GENERAL DESCRIPTION

.
A
structural network
of
steel forms the backbone
of
the

Corvette body. When combined with
the
fiber-glass
re-

inforced plastic body panels,
the
steel-plastic marriage

results
in a
body with increased torsional rigidity
and

greater beaming strength.
Convertible models continue with two roof styles:
the

folding
top
and the removable hardtop. In operation, both

tops function similar to those
of
previous models. Either

top
is
standard and both
are
optional
as
determined by

the top selected
as
base equipment.

be
made
in
order
-

first, then catch adjustments.
Hood

The position
of the
hood
in
relation
to
the hood body

opening and the fender surfaces
is
controlled by the posi-

tion
of the
hinges and position
and
adjustment
of
catch

and bumpers.

by loosening the hinge retaining bolts (lower) and moving

the hood to the limit of slotted holes in hinge strap.

The upper surface of hood may be brought flush with

adjacent surfaces by shimming under hinges and adjust-

ment of bumper screw and catch bolt engagement. Figure

3 illustrates desired spacing.

Hood Catch

The hood catch should be adjusted so that catch bolts

enter lock plates freely and catch bolt length should be

adjusted so that rubber bumpers are slightly compressed

in latched position.

Entrance of catch bolt into the plate may be adjusted

by loosening the three catch bolt mounting screws enough

to allow movement of bolt assembly.

Synchronization of catch release may be made by ad-

justing the cable retainer located at left hand catch plate

assembly.

HOOD ASSEMBLY

Removal

1.
If hood is to be reinstalled, scribe a line around hood

hinge upper strap as shown in Figure 4.

2.
With aid of a helper to support hood, remove screws

retaining hinge straps and support assembly to hood.

If hinges are removed from vehicle, note amount of

shims under each hinge.

Installation

In replacing original hood, align hinge with scribe

marks made on removal and install retaining screws re-

moved from hinges and support.
If adjustment is required, proceed as outlined in this

section under Adjustments - Hood - Hood Catch.

HOOD PROP

Safety Retention Feature

When extended under hood service operations are

anticipated, the hood prop track and slide should be se-

cured by placing a 1/4" bolt and nut through the existing

holes.
This will prevent accidental closing of the hood

that could result in a serious injury.

FRONT EMBLEM

The front emblem is retained by special nuts which

may be reached by raising hood (fig. 5).

be
carefully

checked
for
irregularities
and

To
check

windshield opening proceed
as
follows:

1.
With weatherstrip
and all
foreign material removed

from perimeter
of
opening and with molding clips
in

place, install windshield checking blocks (Special

Tool J-8942)
as
shown in Figure 17. Note that check-

ing blocks must
be
placed over molding clips
to

obtain proper alignment.

2.
Place
a new
windshield glass
in
opening, resting on

J-8942 blocks
as
shown in Figure
18.

3.
Check
fit of
glass carefully. Space between glass

and frame should not vary more than 1/8".

4.
Mark
and
repair
any
imperfections. Recheck
fit as

required.

Installation

1.
Carefully clean
all
loose material
out of
windshield

frame
(fig. 19).

2.
Install
new
molding clips (Item
9, fig. 12).
Both

models
use 13
type
B
clips equally spaced on lower

frame section.
37
Models use 11 type A clips equally

spaced on the top frame section.

3.
Apply
a
bead
of gun
grade body sealer such
as

3M-1170
in
apex
of
windshield frame
as
shown
in

Figure
20.

4.
Install weatherstrip on windshield glass.

5. Starting
at
bottom center
of
glass, insert
a
piece
of

heavy cord such
as
chalk line,
etc. in
groove
of

weatherstrip.
Cut
cord long enough so that about 10"

of free length exists after going around windshield.

Knot ends
of
cord together where they meet at bot-

tom center
of
glass
and
draw knot into groove
(fig.

21).
Tape loose ends
to
inside surface
of
glass
as

shown.

6. Place weatherstrip windshield assembly
in
wind-

shield frame. From inside
of
vehicle grasp ends
of

cord and pull toward you.
It is
wise to have an assis-

tant exert gentle
but
firm pressure
on
outside sur-

face
of
glass
in the
area where string
is
emerging

from weatherstrip. Figure
22
illustrates action
of

string
on
weatherstrip.
Lip of
seal
is
pulled out of

frame apex and over pinchweld flange.

7. When string
has
been removed, carefully inspect

seating
of lip
over entire perimeter
of
windshield,

paying particular attention to corners.

8. Apply
2
beads
of
sealer on outer surface
of
weather-

strip
as
shown
in
Figure
23.
Inject
a
moderate

quantity
of
windshield cement such
as
3M-6699B

between windshield glass
and

as
shown
in
Figure
23.

9. Install lower reveal molding, aligning
it
with mark

made upon disassembly. Refer
to
Figure
12,
View

A, before attempting installation; note that flange
of

molding
and
clips (item
9) at
ends
of
molding must

pass between molding retaining clips and windshield

frame.
li

is met in
engaging molding

flange with retaining clips,
a

be
used
as a

DOORS

ADJUSTMENTS

Door Lock Striker

Door lock strikers incorporate
an
inter-lock feature

consisting
of a
notch
in the
striker into which the lock

bolt housing extension engages. With
the
inter-lock

feature
it is
very important that
the
lock extension en-

gages properly
in the
striker notch
and
that, where

necessary,
the
correct striker emergency spacers
are

used to obtain proper engagement.

1.
To
adjust striker
up,
down,
in, or
out loosen striker

plate screws and shift striker and adjusting plates
as

required, then tighten screws.

2.
To determine
if
door lock striker emergency spacers

are required, apply modeling clay
or
body caulking

compound
in the
door lock striker notch where
the

lock extension engages,
and
then close
the
door
to

form
a
measurable impression in the clay
or
caulk-

ing compound,
as
shown
in
Figure
24.
Remove
all

clay
or
compound when adjustment
is
completed.

When dimension
"A"
from inside face
of
striker teeth

to center
of
lock extension
is
less than 3/16", install

emergency spacers
and
proper length striker attaching

screws.

NOTE:
Dimension
"B"
from center
of
lock

extension
to
inside face
of
striker notch should
.

never be less than 1/8".

If check indicates need
for
emergency spacers,
pro-

ceed
as
follows:
1.
With pencil, scribe position
of
striker on body pillar.

2.
Remove three door lock striker attaching screws and

remove striker
and
adjusting plates from pillar.

3.
To
install, place striker, shims and adjusting plates

within scribe marks
on
pillar
and
tighten screws.

IMPORTANT: Whenever
a
door
has
been
re-

moved
and
installed,
or
realigned,
the
door

SHOULD NOT be closed completely until
a
visual

check
is
made to determine
if
the lock extension/

will engage
in the
striker notch. Where
re-

quired, door lock striker emergency spacers

should
be
installed
so
that door
can be
closed

and
an
accurate check made to determine emer-

gency spacer requirements.

Door Window and Vent Adjustment

To move
the top of the
window
in or
out, the bottom

ends
of
both
run
channels
are
adjustable.
The
rear

channel
is
adjusted
by
loosening
the
lower
of
the two

screws
on the
rear face
of
door, "C" Figure 25, and

moving channel
as
necessary.
The
front channel
is ad-

justed
by
removing
the
trim pad and moving the Channel

in
or out by a
stud
and nut
adjustment, "B" Figure 25.

The
top end of the
rear channel
is
not adjustable in
or

out.

On 19467 models
an
adjustment
may be
made
to the

closed-door relationship
of the
vent assembly
to the

windshield frame. This adjustment
is
controlled
by the

stud-nut assembly "B" Figure
25.

The closed position
of the
window
is
controlled
by

bumper assemblies located
at
each end
of
window frame

as shown
in
Figure
26.

Access
to

screw
may be
gained through holes

The position
of the

viously
