just a note. There are 4 nuts to remove. The one most forget is at the end, where the modling meets the quarter window. As for them being the same. I have a 86 and 90 and they are different. On the 90 the molding extends all the way around past the quarter window to the edge of the door opening. On my 86 it only extends to the quarter windows then there is a different pieice that has the quarter window dew wipe and molding. If you change both I think they will work. I do know that the 91-93 tops are redesigned to sit lower in the car when retracted but I think the top opening in the car is the same size as the older cars.
