Tailgate window dash switch?

My tailgate window dash switch raises the window but will not lower. Key entry works fine. When I take dash apart and inspect switch it works but there is a mechanical problem with it. A piece of plastic has broken off and the switch is unusable in a normal condition.

Any ideas on where and how to obtain a new switch other than the dealer?

I could probably part one out to you. (Other than a boneyeard, someone here would most likely have one to spare.)

This truck I bought didn't have any tailgate glass, so the switch is pretty unusable, to me. (Alternatively, I have a custon-cut piece of plexiglass that serves as the window on the truck....)
