Can you send a photo with the glass down looking into the track with seal installed and one with the glass up and against or into the seal. Still not sure if the glass just seats against the seal or tucks into it. Also does the flat back of the gasket push all the way up into the trim piece and butt against it.
This is a concern of mine as well. The groove for the upper part of the window isnt exactly there... Ive even greased the glass & track to make it easier for the window to move up into the weatherstripping. Ill continue to work it thru...
