64-66 barracuda rear window

Not impossibly difficult. Get the top in and start working the lubricated seal lip over the glass, it will eventually pull itself in. I used wooden popsicle sticks as little pry tools on the gasket lip, the big ones, but they have nylon spudger tools now that are much stronger and wont scratch. You can't break that glass putting it in. Just get an inch at t a time from side to side. I think it took me about 30 minutes. You can have some 60 lb kid sit on it to help seat it.
