Hello, I'm trying to find this part. Do y'all carry it? It's what the sash pivots put on and stays on the track...it is a pretty old window so I haven't been able to find it elsewhere.

We may be able to help, yes. This part is known as a Pressure shoe, or sometimes a friction block. Take a look at the list of parts I made on the right side of this page. One of these may be a match, but it would depend on how well your dimensions match up to ours. You will need to remove yours from the window for the most accurate measurement.
