Figure 71. On Chevelle models with 396 engine, install
the upper hose so that there is at least .6 inch clearance
between the hose and the Delcotron or the inner fender
skirt.
It is important that the power steering hoses be in-
stalled correctly. Hoses installed out of position may be
subjected to chafing or other abuses during sharp turns.
Always make hose installations with front wheels in
straight ahead position. Do not twist hoses unneces-
sarily during installation.
CAUTION: Do not start engine with any power
steering hose disconnected.

GENERAL DESCRIPTION
WHEELS
Chevrolet, Chevelle, Camaro, Chevy n, and Corvette
are base equipped with welded steel wheels. Five studs
with nuts fasten each wheel to the front hub or rear axle
flange. Disc brake equipped vehicles (except Chevrolet
and Corvette) require special 14 inch diameter wheels
with a revised design for clearance, Chevrolet disc brake
equipped vehicles have 15 in. diameter wheels as do all
Corvettes.
Chevrolet station wagons, Chevelle Super Sport 396,
Corvette and Camaro Super Sport 350 are base equipped
with 6 in. width wheels. All other vehicles have 5 in.
width wheels, except Chevy n 100, 300 and 500 Series
Sedans, which have 4 in. width wheels.
Do not install 6 inch width wheels or snow chains on
Chevrolets equipped with rear fender skirts.
TIRES
The factory installed tires on Chevrolet passenger
cars are selected to provide the best all around tire
performance for all normal operation. They are de-
signed to operate satisfactorily with loads up to and in-
cluding the specified full rated load capacity of the
automobile when inflated as recommended in the Vehicle
Capacity Rating and Recommended Tire Inflation Pres-
sures Table (see Specifications).
Optional Oversize and 8-Ply Rating Tires
{Chevrolet and Chevelle Only)
Oversize or 8-ply rating tires are not necessary on
passenger cars for normal requirements. However, an
extra margin of tire service is available when these
options are used at loads up to and including full rated
load.
Optional oversize 4-ply rating and/or 8-ply rating
tires are available on models as indicated in the Tire
Usage Chart (see Specifications). On some models (ex-
ample—Station Wagon), space limitations do not permit
the use of a larger size tire; hence, the 8-ply rating
tire is an available option.
In either case, these tires are applicable to extended
operation at or near full rated load or for trailer towing
when an extra margin of tire service is desired. How-
ever, use of a larger tire or an 8-ply rating tire should
not be construed as permitting an increase in the full
rated vehicle load (see Specifications).
MAINTENANCE AND ADJUSTMENTS
TIRES
Inflation Pressures
To ensure the proper tire inflation pressure for the
owners particular requirements follow the recommenda-
tions in the Vehicle Capacity Rating and Recommended
Tire Inflation Pressures Table (seeSpecifications). Keep
tires properly inflated, and check inflation pressures
periodically. This will ensure the best tire life and riding
comfort, over the full range of driving conditions.
Inspection
Every few thousand miles and at each lubrication, tires
should be checked for sharp objects or stones in the
tread. H tire is punctured, it should be repaired using
one of several repair kits available through tire manu-
facturers1 outlets.
Wear
Misalignment
This is wear due to excessive toe-in or toe-out. In

GENERAL DESCRIPTION
The new front end appearance of the 1967 Chevrolet
and Chevelle passenger cars affects the servicing and
replacement of the chassis sheet metal. Refer to Section
13 for Radiator and Grille service procedures, Section
14 for Bumpers, and Section 1A for Air Conditioning
components. Figures 1 and 2 illustrate the Chevrolet
and Chevelle sheet metal components.
MAINTENANCE AND ADJUSTMENTS
HOOD ADJUSTMENT
The alignment of the hood is controlled by the position
of the hood hinges and the height of the two bumpers lo-
cated one at each side of the radiator support. The ad-
justment at the hood lock must be made after the hinges
and bumpers are properly adjusted. To align the hood
and lock proceed as follows:
HOOD HINGE (Fig. 3)
NOTE:
The body mounted portion of the hood
hinges are slotted to provide up and down move-
ment. The hood mounted end is slotted to pro-
vide forward and rearward movement.
1.
Scribe a line around the entire hinge plate to be re-
positioned.
2.
Loosen the appropriate screws and shift the position
of the hood into correct alignment using the scribe
marks to check amount of movement. Check align-
ment by tightening screws and closing the hood.
HOOD BUMPERS
Adjust hood bumpers so that hood top surface is flush
with the fender and grille top surfaces. Refer to Fig-
ures 4 and 5 for correct sheet metal adjustment dimen-
sions.
HOOD CATCH AND LOCK
The hood catch assembly (fig. 6) mounting holes are
slotted to provide adjustment for the hood lock bolt. Ad-
just the hood lock bolt until hood engages securely when
closed and hood bumpers are slightly compressed.

CHEVROLET CHASSIS SERVICE MANUAL
CHASSIS SHEET METAL 11-12
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.

installed in a new spring by the following method:
1.
Place a closed 6 or 8 inch "C" clamp in a vise or
fasten it to a heavy bench top (bench should be fas-
tened to floor).
2.
Hook one end of spring in clamp and the other end
in hook of a hoist as shown in Figure 29.
