A-Pillar weatherstripping install - HELP...

I think it is supposed to be molded so that it snaps into the stainless piece. I know some reproduction weather stripping doesn't fit like it should. On my Challenger, the weather stripping around the side of the roof is supposed to just snap into place.(no fasteners) The repro weather stripping would just fall out of the channel. I had to glue it in place. Maybe you'll have to do the same thing. I'll see if I can find the weather stripping and have a closer look at it.
