Old painful subject I know . But getting into truly severe frustration over this . The the top of the rear vent window wants to land inward into car when it gets to convert rail —- ,on one side inward on other outward(!) Although a slot on bottom of motor mount tail looks like an obvious adjustment in and out , it cant be , as the regulator has three bolts fastening it hard to sit tight to the inner face of quarter panel inner skin surface , so that body surface sets the angle it comes up out of door , — hard and fast . I did not reassemble this car but starting to think maybe they had factory shims or spacers in there that I don't know about or were lost by PO . The fsm is garbage on this — no info ( by the way I found a lot of wiring diagram errors in that C fsm , kind of thrown together imho .Different pages have conflicting wiring , especially around head light switch, and feeding those kick panel 3 circuit breakers ) . Pix of headlight switch is under “switches” (!!!) many pages away , not on wiring diagram . If you wire as shown the cig lighter will come on with headlights ( only ) But if anyone has fought this rear window in and out alignment issue on convert ( probably similar on hdtp ) let us know , to preserve sanity Top is perfect lands right on pins , roof rail straight , but window trends inward on worst ( pass) side and folds over the weather seal . Fought 57 - 58 hardtops on that before , replacement rubber fir those is not flocked , adds huge problems with drag at end if travel . The convert one IS flocked! small gains! The slot at bottom of motor is to deal with mounting tolerances imho not tip angle of glass . Related, fsm says to get regulator out , run roller to the end , and run out of channel first , then lift out glass . Well , great ! There is no room at end of channel for roller to escape channel it hits the body structure . So unable to get regulator out ( yet) to add a fabricated shim if we wanted to . All you hear about 57 bodies is true . absolutely half baked car is cursed , same one , with 2 weeks + into front regulators, but that is ok now … space between run channels was too tight binding lift motor . Caused by a “ replacement” run U channel too shallow or too thick at bottom of U . Cure is 2 loose pieces of side channel whiskers no U What should take 2 hours takes 2 weeks .
