Duster pop out windows

Hello! I'm new to this forum, and have a question about the 70 Duster pop out windows. Mine are not sealing against the weatherstripping. It's new weatherstripping, which I thought would fix the problem. There's about 1/8 inch of clearance on the top of the glass where it should meet with the rubber. Can this be somehow adjusted? The trim panel around the window isn't installed yet, if that makes a difference.

Thanks alot!!!
