Elaborating a bit - 85 and older has the larger, non-flush mount trim. It's pretty difficult to get off of old windshield without bending it in some way. And almost impossible to remove without breaking the plastic clips that hold it in place. Those usually have to be replaced. 86 and up has 'flush mount' trim.

Here's the real challenge -- any 'new' windshield you buy is for the 86 and up application. It will go into the earlier cars, but the front trim will be different than the rear trim. Furthermore, the older OEM windshields are slightly thicker/heavier than the newer replacement glass. Not sure what implications that has for trying to refit the older trim to a newer windshield.

Last - the newer windshield/trim is slightly smaller than the older trim. So it almost always leaves a 'paint line' when you put the new windshield into an older car. Several folks and some windshield companies remove the new flush-mount trim and replace it with universal trim that is wide enough to cover the paint line. This is the approach I took on mine when I pulled the original 82 glass/trim out (pitted badly) and replaced it with new glass. So, flush mount look and wide enough to cover the paint line.
