I'm trying to install the roof rail weatherstrip on my 68 fastback, the one the window seals against. I can't figure out how it goes at the rear in relation to the windlace and the interior panel. This started out as a parts car years ago so I have never actually seen it together. Tried looking for pictures but none are close enough for me to tell. Does the end of the weatherstrip go under or over the interior trim panel? Does the windlace end up inside the weatherstrip or does it go over and continue on under the interior trim panels? thanks
