Front/Rear window gaskets needed

Hi y'all,

About ready for window installs, but need help on gaskets. Is there a source we mostly like to use? My 74 Dart 2 dr. Special Edition came with a vinyl top, and I'm planning on putting a new one on. I can find front gaskets pretty easy, for about $100, but the rear is confusing, I'm not sure which gasket to order, then I find a site with 2 rear gaskets listed, 1 specifically says for vinyl top cars, and is almost 4x the price!!! $109 for non-vinyl top, $365 for vinyl top cars, is this correct? I don't want leak issues, but $400 for a window gasket seems insane.
