Hi there- thanks for posting!

After looking at your photos, it looks like you have our 15-087 coil spring housing with a pivot cam, and stacked on top are two of our 15-086 tandem coil spring housings. We can see your two top housings are broken. You will need to remove the sash to remove the balance system to see what coil springs are broken and to see the spring weight number stamped on them. This system used Series 180 coil springs. We pulled up some video guides to help you on this page!
