Looking for this plastic part that slides up and down in the side window track with the aid of a spring that attaches to one end. The window sash pin fits into the other end. This part aids in raising and lowering the window.

Hello! This looks just like our 20-022 friction shoe. I think it's a safe bet that the tabs that broke off match the top hooks on ours. Look it over and let me know if you agree!
