General Maintenance & Repairs - Window channel

Anybody know of an aftermarket source for the driver side window channel? You know the channel with the ball fitting that is riveted to the bottom of the glass. Other than the ocasional one on ebay. Thanks

Anybody?

How about your friendly GM dealer? Glass or collision shops should also be able to get a hold of them.

Gm discontinued no longer available, but i will try the other. Thanks
