We're trying to assembly parts of a '55 Crown Vic that came in boxes. First question: On the B-pillar what is the gap on the back side between the felt suppose to be? Ours seems a bit wide and I'm worried about the quarter window sealing correctly. Second: The trim piece that extends back from the B-pillar on the outside that flows down the top of the quarter panel, how dose that attach? Is the a part that screws onto the top of the quarter and then the trim crews onto it? Am I missing something? Thanks...
