I'm not sure how to get them old 2nd gens to seal up. When I was a teenager, if you had a Trans Am or Camaro, especially with t-tops you knew better than to take it into an automatic car wash. If you did you better have a lot of towels. My 77 is no different. I put all new seals in it thinking that it would be better, and it may actually be worse. Now the only way too close the windows fully, is to close the door with a window all the way up. If the door is closed and try to roll the window up there's always a quarter inch gap. Maybe there's a way to fix it, but I don't know how.
