It's a 41 Chevy Pickup if that helps. I never got to see it with glass in it so don't have a clue which way it gets pulled through. The front I think it just held in w/ 2 bolts attached to the hinges on each piece. I think I'll have to weatherstrip the frame, and also put some trim around the windows themselves. It sure would eb nice to have one of these aroudn to look at
