rear window removal 64-66 barracuda
If the rubber is hard (or even stiff) it's usually best to cut (box cutter) as much of the gasket off as possible. On my '69 Barracuda FB I didn't want to risk breaking the glass so I bought a new gasket in advance and cut off as much of the old gasket as possible. If you're going to replace the old gasket then don't be afraid to cut off as much as you possibly can because even if you cut off as much as possible the glass will still be stuck to the gasket that remains. It's almost like it was glued on but in reality it gets stuck after many years of being in contact with the rubber. Once you get everything removed and cleaned I would strongly suggest applying a couple of coats of brush-on undercoating inside the trough. The trough is where water collects and this is where they all begin to rust. On my '69 the trough will hold water and the stainless trim actually keeps the sun from making the water evaporate. So water just sits under there rotting its' way your precious car. By the time you actually see corrosion in that area it's already eaten a hole into the trough.
Truth be told, I actually removed the pegs that were put around the through. You know, the small clips that the stainless attaches to. I removed all those things that give corrosion a place to begin. I sold the stainless (for good money) and installed the glass like all new cars...Urethane. Now with no stainless to hold the water, and no clips to start corrosion, undercoat to prevent rust, it should last forever!!! Did the same thing to the front glass.
Kinda makes the car look more like a drag car!!
GOOD LUCK,
