My passenger side quarter window hits the opening where the u-shaped seal goes in the door jam. It hits on the bottom of the window where the vertical seal passes through the opening. Is there an adjustment for this or do the rollers need to be replaced?

I was looking recently for advice on the quarter window chrome strips and did a search on this forum going far back. Found lots of good advice I think will directly answer your question.

Thanks, I'll take a look.
