That's why I was asking if the 80s is the same or not. If when they changed the roof from round to square if they also changed the shape of the top of the door opening which would have made a difference in the shape of the top of the door and glass.

Yes the glass goes all the way up but when the front of the glass bottoms out at the top of the frame there is still a gap at the back. The sides of the glass seem to fit properly and so does the window, it just looks like the top of the window is a different shape then the frame. Maybe it is a sloppy install because that window was changed before I got the truck but don't know how to adjust it when every other part of the glass seems to fit perfectly. Unless it's just the wrong glass for the application.
