Sliding mechanism for pivot bar

Question

The sliding tilt mechanism that engages the pivot bar on my double hung windows are both broken off at the bottom and no longer engage the bars. The sashes are easily 3 ft each. Sorry I didn't measure them. Enclosed are poor pictures of the remaining assembly. I had tried to wire one up to work temporarily. Please see if they can be recognized. The windows are from US window factory.

Thank you, nick

Hello, Nick. The part in question is called a pivot shoe. It's tough to make yours out in its current condition but the design strongly reminds me of our 15-188. I think this may be what you need but you will probably want to get an undamaged version to confirm.
