Hello,

Your coil springs resemble the 3/4" wide S170 and S171 but we would like to see the pivot shoe that they anchor to in order to confirm if they would be compatible with your hardware. Thank you!

Great, your pivot shoe resembles our 15-192, which uses our Series 170 and Series 171 coil springs. For a 13-1/2" pound sash, I would recommend using one S170-407 on each side of the window. Thanks for posting!
