I did remove the factory 67 Fastback windows and saved both the glass and the weatherstrip, at the time you could not get new 67 weatherstrip.
You should be able to do this with new gaskets, the use of sealant may make it more difficult.
Thanks, I'm not going to use any sealant as I will be pulling them in a year or 2 to strip the entire car and repaint it. I'll use sealer then. This car is my daily driver, that's why I'm trying to not have it down for much time.
