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.

58—-Applying Silqne Primer
NOTE: If the carpet is not extremely soiled,
the carpet may be cleaned in the car by applying
a sparing amount of foaming type upholstery
cleaner with a brush.
CARPETS AND COVERS-ALL MODELS
Removal of front compartment carpeting will require
removal of sill plates and loosening of console trim;
service of these items is covered in this section under
Front End-Cowl Area and Console Trim.
In areas where carpeting is to be cemented, proceed
as follows:
1.
Remove all old carpeting, jute, etc. which may ad-
here to floor after original carpet is pulled up.
2.
Apply 3M-1711 cement or its equivalent, following
directions furnished with package. Be sure floor is
reasonably clean and dry before applying cement.
REAR BODY TRIM
For parts identification refer to Figure 64.
Soft Covers
The soft covering is cemented to the body in rear
window area. Replacement of all or part will require
removal of rear window garnish moldings as explained
further on in this section.
After part to be replaced has been pulled off, all bits
of fabric and other foreign material should be removed
from body inner surface by scraping or through the use
of a solvent such as prep-sol or its equivalent. Both the
new cover and the body surface should be reasonably-
clean and dry before application of cement.
Trim may be applied with 3M-1711 cement or its
equivalent. Follow manufactorer's directions supplied
with package for best results.
Rigid Plastic Trim
The roof trim panel and rear quarter trim panels are
retained by screws as shown in Figure 64. To remove
roof panel it will be necessary to remove dome lamp
assembly.

plastic body panels. The general area around the welding
operation should be protected with wet asbestos or any
other like method (several thicknesses of aluminum foil
makes an excellent heat shield if out of the way of direct
flame).
Straightening of steel parts while still in body must be
done with care. When applying hydraulic jacks or like
equipment which operates by exerting force, bear in
mind that the part being used to brace the stationary end
of tool must be able to withstand such usage and that
fiber glass parts, though tougher than steel, will not yield
or "take a set" as with steel parts, so naturally they
cannot be "straightened". If poor alignment exists due
to collision or other physical damage, check steel re-
inforcements in cowl, roof and sill areas (fig. 69) with
care.
Tracing line of damaging force and checking body
carefully for broken bonds and cracks before, during
and after repairs will pay off repeatedly.
Small cracks and faults in bonds and panels will usually
grow larger if left unattended.
REPAIR PANELS
Body repair panels are illustrated in Figures 66
through 70. Those shown are typical of panels which are
available through Chevrolet parts sources. Procedures
which may be used for installing panels are explained in
the following pages.
Figure 71 illustrates various bonds which will be en-
countered during repair procedures. The legend for
Figure 71 cites typical applications for bonds shown.

2.
Featheredge the repair area with No. 220 wet or
dry sandpaper and finish block sand with No. 320
wet or dry paper, Figure 79.
CAUTION: Do not sand too deeply into fiber-
glass mat. Should it be necessary to cut fairly
deep into the glass mat use the repair pro-
cedure suggested for dents and pits in plastic
panels.
3.
Clean up repair area Prep-Sol or its equivalent,
then finish the clean-up with a tack rag.
4.
Protect surrounding panels by masking before per-
forming paint refinishing operations. Use only non-
staining type masking tapes on Corvette plastic body.
5. Refinish panel as described in paint refinishing
portion of this manual.

or first to be removed; next in order of pro-
gression are Items 5 and 6. Items 3, 4, and 7 may then
be removed.
HEADLINING
Removal
1.
Remove all garnish moldings.
2.
Pull damaged headlining from top (fig. 95).
3.
Soak remaining particles of sponge which cling to
top with Prep-Sol or its equivalent and scrape off
(fig. 96).
Installation
Be sure that top inner surface is clean and dry before
applying cement. Use only cement specified as suitable
for polyfoam material and follow directions supplied
with package. Install garnish moldings in reverse order
of removal.
WEATHERSTRIP AND DRIP MOLDINGS
Figure 97 and 98 illustrate installation of moldings
and weatherstrips on a hard top. Assembly and dis-
assembly of many of these parts will be apparent upon
study of the figures, but do not attempt servicing until
reading the following special information.
Outer Weatherstrips (Item 8, Fig. 97)
Outer weatherstrip is attached to drip moldings with
retainers as shown in view A, Figure 97. To replace
weatherstrip, the weatherstrip drip molding assembly
is removed from the top as a unit and the weatherstrip
may then be removed from under retainers. Replace
any broken or distorted retainers with new parts. Do
not install drip molding-weatherstrip assembly until
familiarizing yourself with Special Sealer information
which follows weatherstrip instructions.
Inner Forward Weatherstrips (Item 9, Fig. 97)
These are cemented to inner side weatherstrips (item
Fig.
96—Cleaning Top Inner Surface
5, Figure 97) and are retained to the top frame with
barbed plastic retainers which are pushed into holes in
frame. Figure 99 shows a cross section of weatherstrip
and retainer.
Weatherstrip Special Sealer
A polyurethane sealer which may be obtained through
Chevrolet parts sources must be applied between top
frame surface and the following moldings whenever they
are removed for service and reinstalled or installed new:
Figure 97 Item 3
Figure 97 Item 4
Figure 97 Item 10
Figure 98 Item 8
Top frame and moldings to be reused must have all
old sealer removed and be free of grease, dirt, etc.
Follow directions supplied with sealer carefully to insure
a successful job. Figure 100 shows sealer being applied.
VINYL COVERING ON REMOVABLE HARDTOP
Removal
1.
Remove weatherstrip assemblies.
2.
Remove reveal moldings.
3.
Place masking tape on clean plastic rear window for
protection. Roof glue solvent will harm the rear
window if it is allowed to come in contact.
4.
Prior to removing fabric cover, application of heat
to cemented areas will permit easier loosening of
cemented edges.
CAUTION: Apply heat by lamps held 18" (mini-
mum) from fabric only until fabric is warm. If
lamps are held too close, or fabric cover is
heated over 200°F, the fabric may loose its
grain, blister, or become very shinyT
5. Loosen cemented edges of fabric roof cover.
