I had a '92 PA, so might be the same. I removed the entire headlight assy to get access to it. There are two thumb screws on top that made it quite easy to remove. The alignment is not affected in doing this either. Good luck.
Need more information, is it a front or rear, side marker even?
Take it to the garage
