I started ripping my vinyl 1/2 roof off before I thought better to see if parts were available 1st. I have a 1977 Grand Prix no in need of the rear window trim for vinyl, opera window trim and some badging. I have scoured the internet and found some badging but not all, and the opera window trim (expensive) Anyone have any ideas on the rear window trim? Are there any other GM cars of same or prior years that will fit? Thanks in advance
