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.

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.

9- Checking Riding Height
not the vehicle riding height is correct.
1.
Place the vehicle on a smooth, level floor and bounce
and rock the front end several times. Raise vehicle,
then allow it to settle to a normal height.
2.
Measure the following two distances (fig. 9):
a. From the floor to the center of the inner pivot of
the lower control arm. (On the Chevrolet and
Camaro, this measurement must be made at the
rear end of the pivot.)
b.
Chevrolet--Measure the distance from the floor
to the lower face of the lower steering knuckle
boss for the spherical joint on the same side of
the vehicle.
Chevelle—From the floor to the outer pivot
which is located 1/8" (.12) inboard from the ball
stud boss at the lower surface of the arm.
Chevy II--Measure the distance from the floor
to the lower ball joint seat.
Corvette—Measure the distance from the floor
to the lower face of the lower steering knuckle
boss for the spherical joint on the same side of
the vehicle.
Camaro—From the floor to the lower inboard
edge of ball seat.
3.
The difference between these two measurements
should be as outlined in the Specifications given at
the end of the book with the vehicle at curb weight
(full tank of gas, spare tire and jack in trunk, no
passengers).
4.
Measure the opposite side of the vehicle in the same
manner. The measurements for both sides should
differ no more than 1/2".
5. To correct the height, springs must be replaced.
These springs do not have flat ends and shims should
not be used.

—Corvette Fuel Tanks
The Corvette
is
equipped with
a
standard
20
gallon
(approx.) tank
or an RPO 36
gallon (approx.) fiberglass
tank
(fig. 21). The
tanks
are
installed
at the
very rear
of
the
vehicle, convenient
for
direct fuel filling into
the
tank.
The
tanks
are
held
in
place
by
two metal straps
at-
tached individually
to a
removable
gas
tank frame
sup-
port.
Two
guides
at the end of
the straps
are
adjustable
for securing
the
straps onto
the
tank support. The tank
support
is
secured
to the
frame rail with flat washers,
lockwashers, bolts
and
nuts.
The
tanks' rest
on six
felt
anti-squeak pads.
One pad
centers
on the
rear frame
crossmember
and one at
each side
on the
same cross-
member.
At the
same rear location two pads
are
placed
on
the
tank
at the
metal support strap (rear) attachment
location
and
another anti-squeak
pad
cemented
on the
support
at
the front
of
the tank.
The fuel tanks
are
equipped with
a gas
gauge metering
unit,
a
fuel pickup, fuel strainer
and
vent line.
If it be-
comes necessary,
the
tank
can be
completely drained
by
removing
the
fuel pickup hose which
is
located
at
the
bot-
tom
of the
tank,
or
by removing the metering
for
quicker
draining.
A pressure vacuum type, positive vented design
cap,
conforming
to
I.C.C. regulations,
is
used on both regular
production
and
optional fuel tanks.
The cap is
inter-
changeable with past model tanks
for
service replace-
ment purposes.

Fig.
26—Gasoline Tank (36 Gallon) Compartment Cover
from the fuel tank pickup at the bottom of the tank, along
the rear frame crossmember to the right frame rail,
extending through the rail at the kickup area and along the
top inside edge of the frame to the fuel pump, Flexible
hoses are located at the fuel tank pickup and at the fuel
pump.
36 Gallon Tank
The 36 gallon tank fuel lines are routed from the bot-
tom of both sides of the tank to the right frame rail
(fig. 20).
Maintenance
CAUTION: Always drain gasoline from the
complete fuel system including carburetor, fuel
pump and all fuel lines and fuel tank if the vehi-
cle is to be stored for any great length of time.
This precaution will prevent accumulation~ol
gum formation and resultant poor engine
performance.
. The fuel lines should occasionally be inspected for
leaks,
kinks or dents, especially when work has been
done on the underside of car or after the car has been
traveling over rough or stone roads at higher speeds.
If evidence of dirt is found in the carburetor or fuel pump
at disassembly, the lines should be disconnected and
blown put. Check the fuel tank strainer for damage or
omission.
Fuel lines are beaded-type ends for connection to
hoses and flared ends for secure metal-to-metal line
connections.
