GENERAL DESCRIPTION
The sturdy front end structure is formed by three
welded assemblies, the left and right hand fender skirts
and the radiator support panel. These units are bolted
together and to the dash panel (fig.
16).
Fender skirts, containing spring towers and support
brackets for control arms, are welded to the reinforced
"closed hat section" side rails. The skirts and rails
are fastened at top and bottom to reinforced areas of the
dash panel. Each skirt and rail assembly is securely
mated ta the body with three bolts at the top, and at the
stub fr|.me butt plates with a four bolt series. Heavy
gauge, formed, reinforcing plates receive the top of the
fender skirt and provide a shimming surface for precise
alignment of front end and body when assembled.
The one-piece radiator support panel completes a box
section when welded to the front crossmember. The
panel is formed to add structural strength and rigidity.
This strong combination is bolted along the full length of
each forward vertical edge of the fender skirts and at
the stub frame ends. Additional strength is obtained from
rigid diagonal corner braces. These open hat section
braces, bolted to side rails and front crossmember,
provide mountings for the suspension tension struts.
Conventional front fenders, grille, bumper and brack-
ets all bolt on to the unit front end structure. The hood
is connected to the front end with hinges that are attached
to the fender skirts.

CHEVROLET CHASSIS SERVICE MANUAL

CHASSIS SHEET METAL 11-13
HOOD ADJUSTMENT
The alignment of the hood in relation
to*
other sheet
metal parts is controlled by the position of the hood
hinges and the height of the two bumpers, located one at
each end of the radiator support. The adjustments at
the hood latch must be made after the hinges and bumpers
are positioned to yield the dimensions shown in Figure
17.
Latch adjustments are made so that effort required
to open and close the hood is reasonable, and hood align-
ment obtained by hinge and bumper adjustment is main-
tained when the hood is closed. Note that the hood latch
is not designed or intended to correct basic hood align-
ment faults.
To align the hood and lock, proceed as follows:
HOOD HINGE (Fig. 18)
1.
Note that the mounting holes in the body-mounted
end of the hinge are slotted to provide up and down
movement of the hood assembly while the hood
mounted end is slotted to provide fore and aft move-
ment.
2.
Scribe a mark around the entire hinge plate which
will be involved in the adjustment.
3.
Loosen the appropriate screws and shift the position
of the hood on the hinge plate the approximate amount
to correct misalignment, using the scribed marks to
check amount of movement. Check condition of ad-
justment by tightening cap screws and closing hood.
Fig.
18 - Hood Hinge - Chevy II
Fig.
19 - Hood Lock, Catch and Support - Chevy II
HOOD BUMPERS
Hood bumpers must be adjusted until hood and fender
line up as shown in Figure 17.
HOOD CATCH AND LOCK (Fig. 19)
Hood lock plate mounting holes are slotted to provide
fore and aft adjustment of the hood lock bolt. The hood
lock bolt itself is adjustable for up and down positioning
of the lock bolt head so that its proper engagement in the
latch assembly may be provided for. The distance that
the lock bolt protrudes out of the lock plate should be
adjusted so that the hood bumpers are slightly com-
pressed by the fully latched hood and so that the effort
required to release the hood catch is reasonable.
FENDER ADJUSTMENT (Figs. 17 and 20)
DO NOT CHANGE SKIRT ASSEMBLY-TO-DASH SHIM-
MING IN AN EFFORT TO ADJUST THE DOOR-TO-
FENDER GAP OR ANY OTHER SHEET METAL AP-
PEARANCE ITEM.
The front fenders are shimmed independently of the
skirt assemblies, unlike conventional- vehicles on which
almost the entire front end sheet metal assembly is
shimmed and adjusted as a unit.
Figure 20 shows the locations of front fender shims.
1.
The rocker panel extension location allows adjust-
ment to make fender outer surface flush with door
outer surface.
2.
The upper or plenum chamber location provides a
means of adjusting fender upper surface so that it
is flush with the upper surface of the cowl.
3.
The locations atop the skirt assembly are shimmed
to close the gap created between the fender mounting
flange and skirt assembly when the plenum chamber
CHEVROLET CHASSIS SWVICE MANUAL

CHASSIS SHEET METAL 11-14
location is shimmed; thus keeping the fender mount-
ing bolts from crushing in the fender mounting
flange.
If shimming is done without the fenders being disas-
asembled, it is suggested that fender mounting bolts
rearward of radiator support be loosened while shims
are inserted and sheet metal fit is checked. Tighten
shimmed mounting bolts first, then all others.

Inspection
If car has been involved in a collision it is advisable
to carefully inspect cowl and dash area for damage.
Check front of dash area following directions in Fisher
Body Manual. Pay particular attention to welds, cage
nuts,
weld nuts and skirt mounting surfaces. Cage and
weld nuts may be repaired by outright replacement (the
best method); or by the installation of spiral thread in-
serts.
If the spiral inserts are used, follow the instruc-
tions furnished by the manufacturer.
