Mike, sounds like progress, glad you revived this old thread, lots of good info here! I assume you removed the cat whiskers already....if not, iirc, at least the outer one will get in the way. If the whiskers are removed, I imagine there COULD be some contact between one of the window frame channels and the head of a screws that secures that exterior sill trim...there are several screws and they all stick up a bit. It probably depends on where the screws are located exactly, and by how much they're protruding. By the looks of the holes on my trim, DeTomaso/Ghia didn't use any drill templates to make it a consistent operation! Good luck, I'll keep thinking, this is a best guess for now...
