SHEET METAL ADJUSTEMENTS
In o rd e r to have the p ro p e r o p e ra tio n and
appearance of sheet metal components, it is important
that certain fits and gaps between components be
maintained. The gaps given in this procedure are
suggested as the best alignment for these components
(figure 13).
In aligning sheet metal, it is best to start with the
rearmost component, and work forward.
1. Starting with the fenders, align the rear edge of
each fender to the rocker panel, and the door.
The gap between these components should be 5
mm ± 2.3 mm (0.19-inch ± 0.09-inch). This
adjustment should be accomplished by moving
the fender forward or rearward. The surface of
the fender should be flush with the rocker panel
and the door. Add or remove shims to perform
this adjustment.
2. Align the fender to the cowl vent grille to obtain a
gap of 4.6 mm ± 1 mm (0.18-inch ± 0.03-inch).
The surface of the cowl vent grille should be flush
with the fender surface.

HOOD REPLACEMENT

• Raise and support the hood. Place a protective
covering over the fenders, and the cowl vent
grille.
• Mark the position of the hinges on the hood.

• Align the hood with the previously made marks.

• Bolts to 17 N m (13 ft. lbs.).
• Remove the protective coverings, and lower the
hood.
3. Align the hood with the cowl vent grille, so that
there is a gap of 8 mm ± 1 mm (0.31-inch ±
0.03-inch) between the rear edge of the hood and
the front edge of the cowl vent grille. The hood
surface should be flush with the cowl vent grille
s u rfa c e
(+ 0.00-inch-0.06-inch).
4. Align the left and right edges of the hood so that
a gap of 4.6 mm ± 1 mm (0.18-inch ± 0.03-inch)
exists between the hood and the fenders. The
hood surface should be flush with the fender
surface within + 0.0 mm, -1.5 mm ( + 0.00-inch,
-0.06-inch). If this gap is difficult to obtain, and the
hood appears to be cocked in between the
fenders, the radiator support may need to be
shifted. By shifting the radiator support, the entire
front end sheet metal can be aligned as a unit.
Loosen the support to the frame bolts, and shift
the radiator support to obtain the proper gaps.
Then, while holding the support in position,
retighten the radiator support to frame bolts.
5. Align the front face of the hood to obtain a gap of
4.6 mm ± 1 mm (0.18-inch ± 0.03-inch) between
the hood and the radiator support upper panel.
The hood bumpers on the top of the radiator
support should be adjusted to give the proper
support to hood gap. The surface of the hood
should be flush with the radiator support upper
panel (not the grille molding).
