'86 to '95 should all be the same, but double check with the manufacturer once you've found one to be certain.
As far as models go, they should all be basically the same with varying features (dome lights, map pockets, rear vents, ). If you're going used, look for seriously tweaked, out-of-square (make sure the rear window closes with no gaps, as well as the obvious damage.
When you install it, there will be some out-of-square issues, but you can do some adjustments on the window to fix that. I think we've got a little "white paper" that talks about this on our web site.
