I'm looking for a window stop for my passenger side window. Seems like part # 20216825 has been discontinued in 2013. Does anyone know where I can get a hold of one or have any other alternative for resolving the window issue I am having with my 84?

If that doesn't work, this will:

You could also improvise with some parts from the hardware store if that is the part I think it is. I used a cabinet bumper and a bolt and threaded nylon washer. There is also a thread on here where someone used a bicycle brake shoe.

 

Thanks for everyone's responses. I believe the part I am looking for is what prevents the window from rolling up to far. The part that I need to replace is attached. Any help would be great. Thanks.
