I have to cut out a window hole in my rear door.
I don't have the glass and don't plan on getting it. I just need the factory sized swing-out window opening.
I want to make the right size cut though just in case I end up getting the factory sized swing-out window.
I bought the factory weatherstrip for the swing-out style Chevy Express / GMC Savana rear door glass for my model year. I think the rear doors are very similar from 1996 to 2006.
Problem is that I don't know where to cut.
The factory weatherstrip is flexible.
Also, I don't know how to position the weatherstrip.
It has two notches on the gasket side. Would they be positioned at the top or the bottom?
Back to the door cutting.
I'm guessing I'd cut within the outline provided by the inner metal panel.
I have an inner trim panel that I might use. The window opening dimension on the trim panel is approx 1/2" smaller all the way around than the inner metal panel of the door. I guess I could try fitting the weatherstrip on the trim panel window outline just to see if the weatherstrip is larger or smaller.
I'd really appreciate any help. Maybe a couple of photos of the weatherstrip/gasket from the inside of a van just to point me in the right direction.
