anyone know if a 91 crx si window will fit a 89 si?

 

Why not just take some measurements? Measure both windows and see. I know the doors aren't the same size, not sure about the glass though.

 

Yes, and the doors are the same size as well. The only difference in the actual door is the middle trim piece. All 88-91 doors are the same size. The glass in 88's is bigger because there are no seatbelts in the doors. The trim on 88-89's is different from the trim on 90-91's.

 

ok so it will fit right? anything from 89-91 ?

 

did you just say that 88/89 crx doesnt have door mounted seat belts?
