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.

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
bumper retaining
screw
may be
gained through holes
"D" and
"E"
in
Figure

Door Hinges
The position
of the
door assembly in the body opening
is adjusted
by the
striker plate position covered
pre-
viously
and the
position
of the
door
on
the hinge rear
