Coil balance and unknown part (pin?)

Question

We have a window that will not stay up.  I have uploaded photos of the coil spring but am unsure which part(s) we will need.  Please advise.

Thank you for reaching out to us. Your shoe matches the 15-177, which uses the S152 coil springs (sold separately). You will have to check the old spring band for a stamped weight code. If you need new coil supports, see the 15-143, 15-144, and 15-145. These "sandwich" over each spring.

We can't be entirely sure of the pivot bar since it's damaged, but the 26-226 comes to mind. Review the specifications and see how they compare with an undamaged version of your old pivot bar.
