Adjustments
Hinges
The folding top compartment lid should be adjusted so
that in the closed position the surface of the lid is flush
with surrounding body surfaces and space between lid
edge and body is 1/16" to 3/16" at sides and 3/16" to
1/4" at rear. Whenever lid position is changed on hinges,
lock engagement must be inspected and adjusted if neces-
sary. Adjust hinge position as follows:
1.
Scribe a line on lid surface following contour of hinge
strap.
This will ease observation of lid movement
during adjustment (fig. 51).
2.
To raise or lower top surface of lid, add or remove
hinge shims.
3.
To adjust spacing between lid edges and body, loosen
hinge-to-lid screws and shift lid as required.
Lock
Lock engagement may be adjusted as follows:
1.
Striker plates may be shimmed to adjust the depth
of lock engagement in striker plate. When this ad-
justment is made, release of lock should be tested
and adjusted as required.
2.
Release of lock may be adjusted by loosening lock
assembly retaining bolts and moving lock in ap-
propriate direction to the limit of slotted holes in
, lock base. Further adjustment may be gained by

material (using a sawing motion) with the steel wire;
up side of window, across top, down opposite side,
and across bottom of window.
6. Remove old glass from window opening.
7. Using a sharp scraper or wood chisel, remove ad-
hesive caulking material from body pinchweld flange.
NOTE:
It is not necessary to clean off all the
old caulking material completely from body
opening; however, there should not be any loose
pieces of caulking material left in the opening.
8. Check all reveal molding retaining clips for damage
(24 required). Replace those that are bent or dis-
torted with clips provided in kit.
9. Using weatherstrip adhesive, cement rubber spacers
at bottom, sides, and top of window opening. The
step-type spacers are used at bottom and sides, the
flat type are used at the top, sides, and bottom of
window opening as shown on Figure 55.
10.
Using suction cup holders, position replacement
glass in body opening. Carefully check relationship
of glass to body pinchweld completely around open-
ing. The overlap of glass to body pinchweld and re-
taining flanges should be equal with a minimum over-
lap of 3/16M. Where necessary, position shims under
the lower spacers to obtain required overlap of glass
to body upper and lower flanges.
11.
After proper glass to pinchweld relationship has
been attained, mark position with grease pencil on
glass and body as shown in Figure 57.
12.
Remove glass from body opening and place on pro-
tected surface.

1/2 inch from edge of inside surface of glass com-
pletely around glass. Then apply a film of silane
primer to inside edge surface completely around
glass,
also apply silane primer to sealing surface
of pinchweld as shown in Figure 58.

15.
Mix adhesive caulking material and accelerator
] thoroughly according to directions on container.
NOTE:
Once caulking material is mixed, there
will be approximately 35 minutes of working
time with the material. Subsequent steps should
be performed immediately after caulking ma-
terial is mixed.
Place caulking material in cartridge as shown in
Figure 59.
Carefully apply a smooth continuous bead of caulking
material on inside surface of glass next to edge
completely around glass (fig. 60). Caulking material
should be approximately 1/4 inch wide at the base
and form a pyramid 3/8 inch high. If during appli-
cation the pyramid collapses, wait about 2-3 minutes
for material to set up. If an air bubble is encoun-
tered in material back up the applicator and apply
sufficient material to fill void and to dispense the
bubble before continuing.
The reveal molding clips are self sealing and do
not require sealing before installing the rear glass.
With aid of helper, lift glass and carefully position
glass on spacers, matching up marks on glass and
body as shown in Figure 61.
Press glass lightly to set caulking material to rear
window opening flanges. Paddle material where nec-
essary to insure proper seal.
Watertest rear window immediately using a cold
water spray. If any water leaks are encountered, use
flat bladed screw driver or stick and paddle caulking
material into leak point to correct leak. Correction
of leak is usually more effectively performed by
paddling material from inside the body.
CAUTION: Do not run a heavy stream of water
directly on caulking material while the material
is still soft.
22.
Install the reveal moldings in the following sequence:
Top,
sides, lower and the caps in each upper corner.
23.
Carefully remove masking tape from inside of glass
and install garnish moldings.

Procedure for Cleaning Coated Fabrics
Care of genuine leather and coated fabrics (includes
vinyl coated formed headlining) is a relatively simple
but important matter. The surface should be wiped oc-
casionally with a dry cloth, and whenever dirt accumu-
lates,
the following cleaning instructions should be used:
1.
Lukewarm water and a neutral soap should be used.
Apply a thick suds, worked up on a piece of gauze or
cheesecloth, to the surface.
2.
The operation should be repeated, using only a damp
cloth and no soap.
3.
The surface should then be wiped dry with a soft
cloth.
Polishes and cleaners used for auto body finishes,
volatile cleaners, furniture polishes, oils, varnishes or
household cleaning and bleaching agents should never
be used.
Procedure for Cleaning Carpet
Thoroughly brush or vacuum the floor carpet, in many
instances the floor carpet may require no further clean-
ing. If the carpet is extremely soiled remove carpet
from car and thoroughly vacuum to remove loose dirt;
then with a foaming type upholstery cleaner, clean ap-
proximately one (1) square foot of carpet at a time. After
each area is cleaned, remove as much of the cleaner
as possible with a vacuum cleaner. After cleaning the
carpet use an air hose to
"fluff"
the carpet pile, then
dry the carpet. After the carpet is completely dried,
use an air hose to again fluff the carpet pile.
