Ok guys I need some help. I'm looking for a part that is discontinued and I cant locate any aftermarket stuff on it. It is GM part #10198202 Retainer Asm-Front Side Door Window Channel or RETAINER, Front Door Window Sash

https://www.gmpartsgiant.com/parts/c...~10198202.html

Its the front guide for the glass. The rubber is broken on mine so there nothing to guide the glass. I found a used one on Ebay but it looks worst then mine. Any help would be much appreciated.

Look around online for a generic window guide weatherstrip. It doesn't need to fit the channel all that well, or the window, it just needs to be U shaped and wide enough that it won't drag, then glue or if you have the staple gun from hell that GM had, staple the rubber into the channel and you're done.

See if any of these come close... https://www.rockauto.com/en/tools/bo...+channel,12412

Thanks a million, i was completely lost, im sure one of those will work, I'll size it and see which one will work, thanks again.
