68 Dart Are the weatherstrips supposed to be glued in place or are they supposed to lock in and hold themselves? When cleaning up the retainer, it looked like there was some glue residue in a couple places. If I had to guess, I'd say the thin piece that attaches to the retainer (before the retainer is installed) should get some adhesive. The molded piece that wraps around to the side window area(installed after the retainer is screwed to the header) locks itself in and doesn't need adhesive. Am I correct? When I removed the retainer from the header, there was nothing between it and the header in the way of a seal. No foam or anything. I'm not sure if someone had been there before me and removed anything or if nothing is supposed to go between the two pieces.
