69 barracuda fastback back glass gasket

buy the seal and have a glass guy install the window is the best advice I can give. My glass guy was freaking me out the way he was beating the top in, I wouldn't have thought to be that rough with it. He said I've done tons and this is how it's done. I installed the clips first. Since yours is a 69 and you removed the glass you must have the clips in for the trim already.
