Hi all, I've just purchased a 70 Mach 1 that is missing a couple of hard to find interior parts, and I'm hoping someone here can point me in the right direction. I need the "window channels", the metal/chrome pieces that fit around the door/window frame that the weatherstripping fits into. Also, I'm looking for the plastic piece that goes over the headliner, and across the top of the windshield- in black if possible. Anyone have any ideas where I can find these pieces? NPD does not have them, and I was told by an interior restoration company that I'd need to find them off of a donor car. Thanks in advance.
