I seen that you were looking for NOS door weatherstriping, if it is the ones that go around the door itself, I have the left and right (NOS still in the boxes, one box never opened).
The part numbers are C9ZZ 6520531-A and C9ZZ 6520530-A. Some other NOS stuff I have is cowl vent seal (C9ZZ-16740), Quarter window verticle seal for F/B (D0ZZ-63214A14-A), 3-vaccum tree temp switch ( DY 165-A).
I have a 67 GT390 F/B that is all original, but I'm always looking for parts for it. Food for thought. Let me know if anything will work for you. Contact me at [email protected] Thank's. Kelley.
