Leaking (air) vent windows

[TommyD11730]

Been driving my 84 K2500 all summer with the windows down. Now that it cooler I'm driving with the windows up. You guessed it drivers side vent window roars from an air leak. So I'm wondering has anyone had any luck buying replacement gaskets and rebuilding them? I see the kits list 1 or 2 piece seals. Can I determine which I have without pulling the window out of the door.
Thanks!

Used their gaskets/westherstrip, or???

Yeah, they have some shaped vent window gaskets. Seemed to work well. Also used some in a few other places - all are of decent quality and fit.

I do not know this personally but I have heard people trying the one piece gaskets do not work well and to use the original 2 pieces style with the rivet kits
