Hi folks, I need some opinions, advice, or some good moral support. The guide that is bonded to the front edge of my passenger window came off. I used epoxy on it, which worked for a while. I bought a salvage replacement and now am asking what kind of can of worms I am opening to replace the old window? This is on my 90 red coupe, saddle interior, with VIN 1G4EC13CXLB908369. This car came with both a cassette and cd player. It runs and drives great but would be nice to be able to roll down both windows. Thanks for any help.
