63 Dart rear glass rubber seal

Found mine at Mopar Muscle in mich. I got frt and rear from them. They fit great and i dont have leaks anymore. I got all the rubber trim pcs through them, i believe they make their own products
Do you have a link or contact info for them? Just googled Mopar muscle but never found them.

Do you mean Detroit muscle technologies? If so I have been looking at their website and they don't list one for the dart.
