Hello,

Take a look and compare our 15-111 pivot shoe, Series 160 sash support system, as well as the related items on our product pages to your original hardware.

There should be a stamp near the end of the coil that anchors to the pivot shoe, which will indicate the strength option that you need for the S160 coil springs. Thank you!
