Can anyone tell me the correct procedure to adjust the hardtop for proper fit on a1985 380sl.When installed ,the passenger door glass slightly hangs up at the uppermost rear edge. The drivers side is fine. I understand that dealers adjust the hardtop for proper fit.What do they do?The windows are fine with the soft top up,and I have been told that hardtop must be adjusted to fit the windows.How can I do this?Help please!
