I believe I got the Drip Rail off OK, I used a Can Opener and some small Plastic Pry Bars, but that Vertical Molding near the back of the Rear Quarter Glass was impossible on the Impala Custom. I came to the conclusion that if I tried any harder, I would just end up ruining it. So there I left it. I also posted that problem on different sites and got no answer at all.
I believe taking off the weatherstripping channel will help though. On the main drip rail anyway.
