i have some metro seals i also bought from fran bishop,,,roof rail and wing window seals,,i havent installed either of these yet,,,,and they wer at the time and may still be the only company making wing window gaskets for the early A,,i thought i struck gold when i got wing window gaskets,,
i had bought a n.o.s windshield gasket from chrysler back in 1979,,it never fit properly,,,but took me a long time to figure that out,,,,and that was a factory replacement gasket,,,,but who knows who made it in 1979..
but i have purchased a new repoped front wind shield gasket and the maker is percission,,,i have not installed it yet,,,,but have seen them installed and i have measured it and compared it to the orignal gasket,,, its appears to be perfect,,,,
