Trying to identify what coil to replace

Question

Hello, I'm trying to replace the coils on this window, one side had three coils I can see and the other had two. I would've removed all parts but will have to notch the window to get them out. So will do that when I have the parts

Your coil balance pivot shoe looks a lot like our 15-191 Heavy Duty Pivot Shoe. Carefully compare the measurements to your existing pivot shoe to confirm that this is the right fit.

The compatible coil spring is the Series 160 Coil Balance. Since your window had a different amount of coils on each side, my best suggestion would be to confirm the exact weight of the sash. We'll be able to use the sash weight to determine the coil springs you need.
