Windows coil balance parts

Thanks for reaching out to us. We'd be happy to help with this. We'll just need more information to narrow down some options. Can you show us the front of the pivot shoe? It'd also be helpful if you could write out the thickness and width. 

I believe you have a Slocomb window. They changed the tip of the pivot bar, the 26-129, but it will fit the new pivot shoe which is the 15-177. If the springs are fine, you can reuse them or purchase the S152-4 and S152-7 coil springs.

We're happy to help. Good luck with the repair!
