I need to change the RH outside manual mirror on the 98 Brighton. I know that 1995-99 should interchange, but what about first gens (90-94)? Of course the local u-pull-it has lotsa oldies but no second gens. Thanks.

Not sure where you are in PA, but Harry's in pennsburg had a few of those mirrors when I was there last week. I think they were power though. As far as I know legacy mirrors interchange 95-99 only.

Last summer I had to replace the passanger door mirror on wife's Legacy OBW. I was told only 95 to 99 models interchanged. There is one screw that is nasty to remove. You really need to use a 3/8" drive with an extension bar and a phillips screw driver tip to gain enough leverage to loosen. A regular phillips screw driver won't give you sufficient leverage. I paid $75 for a used mirror, still think I paid too much, but not much selection at wrecking yards when I went looking.
