Roof alignment is obtained by means of fore-and-aft and up-and-down adjustments made at the right and left power-link adjustment screws. In addition, the height at the roof front only can be changed by turning the right and left control link adjustments.
Turning screw at power-link pivot bracket in trunk well adjusts roof fore and aft, up and down.
To align the roof to the windshield header and rear quarter, and to obtain proper timing of lock engagement, loosen all roof-lock assembly mounting screws just enough to retain lock washer contact with the mounting surface. Push in on the actuating switch until all the roof locks stop. This should securely lock the roof.
If the roof does not align and lock down, operate the actuating switch to move the roof to the point of lock engagement. Disconnect the two flexible driveshafts at the roof motor to elimate drive tension on the roof linkage. Remove the bolts from the base of the roof lift jacks, then loosen the lock nuts and back off on both control link adjustment screws. Loosen the four adjustment nuts on each power-link pivot bracket, but be sure to retain lock-washer tension.
Control-link adjustment to the rear of power-link pivot bracket changes roof's height at front only.
Now lock the roof by using a jumper wire at the roof-lock power relay, adjusting the roof manually, if necessary, to align the locks. With the roof aligned and locked, unlock it at the unlock power relay, then relock it at the lock power relay.
With the roof locked down, adjust both rear power links by turning the fore-and-aft adjustment screws so that the slack is just removed, then tighen an additional half turn. Tighten the retaining nuts on each power link pivot bracket.
Turn the control link adjusting screws to contact the control link, then tighten the screws just two additional turns and tighten the lock nuts.
Loosen the lock nuts on the roof lift jack, slide the notched washers up and out of the notch in the shafts, then turn the jack shafts as required to align the jack bottom bolts. If necessary, turn the flexible driveshafts to obtain alignment. Install the bolts, position the notched washers and tighten the lock nuts.
Partially unlock the roof and tighten the front roof lock nuts and the upper and lower rear locks. Then raise the roof and tighten the upper lock components. Tighten the pivot mounting screw first, then the movable screw. In checking engagement, the front locks should engage the lock nut slightly before the rear locks engage.
The pitch of the roof can be adjusted, if necessary, at the control-link adjusting screws. This adjustment should be made with the front of the roof supported on a block at the header to take the weight off the linkage. One turn on the adjusting screw gives 3/16 in. movement at the header.
To make a major rear roof lock adjustment, loosen the two bolts retaining the lock screw bracket in the roof panel and adjust the screw and bracket fore or aft as required. Loosen the two bolts retaining the lock nut assembly to the quarter panel and adjust the assembly sidewise into alignment with the lock screw. Loosen the set screw and adjust the lock screw in or out of its mounting bracket as needed.
If a major front roof-lock adjustment is required, loosen the screws retaining the lock screw and transmission assembly, and pivot the assembly fore or aft at the inboard bolt. Loosen the lock nut assembly at the header and adjust it sidewise into alignment with the lock screw. Loosen the set screw and turn the lock nut in or out of its housing with a suitable tool or one available specially for this purpose.
Do not attempt a trial locking of the roof unless the set screws are properly tightened. When replacing front roof lock nuts install the right lock nut with the set screw to the right of the nut, and the left lock nut with the set screw to the left.
