Hi,
     If I'm not mistaken the body style, and indeed the hinges in
question here, (with only minor trim differences, ie. the hinge may
look slightly different,) but the actual dimensions, mounting holes
etc. should remain the same from 75 or 76 until 1992.

Good luck,

P.S. I have a 1990 245 for parts. If you can't find the hinge that you
need, drop a line back, and I'll try to help out. a '90 should be
definately the same as a '91. I'd be glad to pick the part and get it
to you if needs be
