I found these numbers on the plastic parts I believe they may be just patent numbers I did not see any numbers on the metal Springs that are broke.

Hello,

Take a look and compare our 15-111 pivot shoe that works with our S160 coil springs to your original hardware. If you can't find the stamp on your original coils, you'll need to weigh the sash and divide the weight by the number of coils in the window to choose to correct strength option. Thank you!
