DOOR SILL PLATE AND MOLDING
Figure 49 shows assembly details of both the door sill
plate and molding. The sill plate which retains the car-*
pet, the cowl trim windlace and lock pillar front edge
trim are retained to the body by six screws.
The molding assembly, which replaces a rocker panel,
is quickly and easily replaced by removing 10 retaining
screws. The sill molding retainer is also fastened to the
body with screws.
REAR END
FOLDING TOP COMPARTMENT LID
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
moving cable retainer in appropriate direction.
Hinges
(Refer to Figure 52)
Removal
1.
Scribe around hinge as shown in Figure 51.
2.
Hinge may be removed as an assembly by opening
top compartment lid fully and removing 3 retaining
screws. Note number of shims found between hinge
frame and compartment floor.
3.
To remove spring from hinge assembly, close top
compartment lid as far as possible and insert Tool
J-9559 between expanded coils in spring. Opening
top compartment lid fully will allow removal of
spring as shown in Figure 53.
4.
As soon as spring is removed, insert long bolt sup-
plied with J-9559 through holes in end of tool, pass-
ing it through spring, and install nut on bolt.
Spring may be removed from J-9559 or J-9559 may be
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 chain hoist, "cherrypicker" or equivalent,
as shown in Figure 54.
3.
Stretch the spring enough to allow insertion of
J-9559. Install through bolt if spring is not to be in-
stalled on hinge at once.
installation
1.
Install same number of shims as removed or, if
repairing collision damage, etc., position hinge in
compartment, install upper mounting screws, fill
gap between floor and hinge frame with shims and
install lower mounting screw.
2.
If spring has been removed from hinge, install
spring in J-9559 and place spring on hinge with com-
partment lid raised; closing lid releases J-9559 for
removal. Upper end of spring should rest in one of
three notches yielding best lid operation. About 3
pounds pressure should be necessary to close lid.
Lock
Removal
1.
Remove cable mounting clamps. Remove retainer
from control cable assembly and disengage cable
from control.
2.
Scribe a mark on lid following outer contour of lock
assembly.
3.
Remove 3 lock assembly retaining screws and re-
move lock from compartment lid.
Installation
1.
Place lock assembly on compartment lid within
scribed line and install retaining screws.
2.
Install end of cable in control assembly and fasten
retainer securely.
3.
Test operation of lock thoroughly, adjusting if neces-
sary as outlined in this section.

For parts identification refer to Figure 55.
1.
Remove the 2 rear window garnish moldings by re-
moving the 14 attaching screws.
2.
Pry molding caps from reveal moldings.
3.
Carefully remove lower, side, and top reveal mold-
ings after marking their position on body with tape.
4.
Secure one end of steel music wire to piece of wood
for handle. Insert other end through caulking mater-
ial at lower corner of rear window; then secure end
of wire to another piece of wood (fig. 56).
5. With the aid of helper, carefully cut through caulking
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.
13.
Clean inside edge surface of glass so that glass is
free of any foreign material (oil, grease, etc.).
Using 3/4" masking tape, place tape approximately
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.

Cut off painted portion of cartridge nozzle along

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.

weatherstrip assembly, and by neoprene base cement
which is applied between weatherstrip and side rail
surface.
When replacing weatherstrip remove all rust, old
cement and foreign material from the surfaces to be
cemented, to assure successful bonding. Use only good
quality neoprene cement suitable for weatherstrip
application.
Header Weatherstrip
Weatherstrip assembly is retained to the header panel
by a combination of studs, sheet metal screws and special
fasteners as shown in Figure 112, along with neoprene
base weatherstrip cement.
Figure 99 shows' a cross section of weatherstrip taken
