You helped me originally back in
this thread .. and since then I spoke with cudavert who originally assembled the car. He informed me it was a vert gasket, and that the correct 67 gasket was unavailable (and sucked).
It would be awesome to know it's a 68-69 gasket because that would be one less thing to buy. I don't mind spending the 600 or so to have windows that don't leak, and have nice stainless trim. Thank you for all the info you've provided. You're clearly one of the brightest stars on this forum.
