Weather Strip Seals

Can someone tell me a good place to get weather strip parts for a 1965 Dart GT?
The seal between the a frame pillar and door has gone bad.
Have looked at several sites, but the only one that I think has them is Just Mopar.

Most of the vendors who stock that much weatherstripping products will have them available. To my knowledge, there is only one manufacturer of the A-pillar seals for your 65 A-Body hardtop and that is Metro. I know that we offer them at $50.00 per pair.
