(3) Mark all bolt and hinge attachment locations
with a grease pencil to provide reference marks for
installation. When installing hinge, align all marks
and secure bolts. The trunk lid should be aligned to 4

INSTALLATION
Reverse the preceding operation.
CONVERTIBLE TOP ADJUSTMENTS
When a convertible top component is aligned to
proper fit and finish specifications, weatherstrips and
seals will not always make proper contact. In these
cases, the use of shims, spacers, caulking putty and
foam adhesive backed tape will be required to gain
proper seal compression. Align weatherstrip and seal
channels or retainers so the contact surfaces are
smooth and make full contact with mating surfaces.
A paper strip, equal in size to a dollar bill, should be
able to be drawn through the contact surfaces with-
out tearing the paper. A reasonable amount of effort
should be required to pull the paper through. Bolt on body panels should be aligned to the weld
on body components. The door should be aligned to
the quarter panel, rocker panel and A-pillar. The
gaps between panels should be as equal as possible.
When the door is fitted properly, the door glass can
be aligned to roof rail and A-pillar weatherstrips. Af-
ter verifying the door and door glass alignment, the
quarter glass can be aligned to the door glass and
rear roof rail.
DOOR GLASS ALIGNMENT
GLASS UP-STOP
The door glass up-stop bumper can be adjusted to
raise or lower the glass in the full up position. (1) Remove door trim panel and water shield.
(2) Loosen up-stop bolt.
(3) Adjust bracket.
(4) Tighten up-stop bolt.
DIVISION BAR ALIGNMENT
The rear of the glass can be aligned up or down by
shifting the bottom attachment of the division bar.
Division bar adjustments are small and may not be
possible on some vehicles. (1) Remove door trim panel and water shield.
(2) Loosen blot holding bottom of division bar to
inner door panel. (3) Loosen bolt holding division bar to door inner
panel below stationary glass. (4) Shift division bar forward or rearward to
achieve proper adjustment. (5) Tighten bolts.
CONVERTIBLE TOP LATCH HOOKS
(1) Disengage top latches and raise top halfway.
(2) Loosen set screw locking latch hook in position.
(2) Rotate latch hook in or out to adjust latching
effort and roof header weatherstrip compression. (3) Verify latching effort and tighten set screws.
ROOF RAIL WEATHERSTRIP RETAINER

roof rail. (3) Shift quarter glass inboard or outboard, for-
ward or rearward to achieve proper alignment. (4) Tighten nut to hold top of quarter glass to rear
roof rail. (5) Verify door glass operation and weatherstrip
sealing.
ROLLER BRACKET
The roller bracket controls the in and out move-
ment at the bottom for the quarter glass. (1) Remove quarter trim panel as necessary to
gain access to the bottom of the quarter glass. (2) Lower convertible top.
(3) Loosen bolts holding roller bracket to quarter
panel reinforcement. (4) Align roller bracket to reduce quarter belt
weatherstrip contact when top is raised and proper
sash weatherstrip compression against the door
glass. (5) Tighten bolts to hold roller to quarter panel
and verify top operation and weatherstrip sealing.
TOP STACK DOWN-STOP
Adjust down-stop in or out to set top stack down
position height.
CAUTION: Avoid setting top stack position too low,
top cover can be pinched and cut between wheel-
house and fourth bow. Seal base of down-stop with silicone after adjust-
ing to prevent water leaks.
TOP STACK UP-STOP
Adjust up-stop in or out to change the contact with
the rear rail. This will effect the fore/aft position of
