Window retention track

Thanks for posting. This is a coil balance system. It looks like our Series 140--the 7 stamp suggests you need the S140-07 7 pound assemblies. For the pivot bar, see if either the 26-398 or 26-405 match yours; compare with an undamaged version to confirm, Let us know if you have further questions.

That appears to be the Series 140 that I recommended previously. If you haven't had a chance to review it yet, I highly recommend you do so. I've linked to its store page here in my responses.
