Your 1989 (assuming it is a last of the 3.2s) might have a plastic trim around the windshield and not aluminum. This often gets destroyed on the way out. You can replace it with a factory aluminum piece from an 87 and earlier or the same plastic one available from the dealer (cheap).

I have never regretted changing a windshield on a car that is ever driven at night. If pitted, polishing won't work adequately.
