1967 Dart windshield seal

Frustrating thing is I have a repop lockstrip installed, that was included when we bought the 67 fastback cuda. I swear the stuff shrunk, when I spoke to Joel from Precision he said that their product doesnt shrink and would warranty. I had no receipt so no warranty.
Mylar lockstrip takes a specific gasket. You cant mix n match. Its pricey either way, lockstrip front and back for me is approx $600-800. Change to 68/9 stainless requires new gaskets, clips, windshield removal and reinstall.
Good luck
precision is even MORE proud of their products (keep in mind this will be the last one you buy in your lifetime)

looks like Just Mopar is selling Precisions part (part numbers are almost the same, I'd call both and see if any difference)
