Coil balance parts

A handy person from 44212 says:
I am looking for replacement coil balance hardware. The windows are builder grade, with no marking that I can find. the window dimension is 58" tall X 35" wide. The lower sash is 30" tall X 35" wide. The coil support is 4.5" long, and 1.25" wide. The brake piece is 1.5" tall X 1.25" wide. The coil support plastic has basically disintegrated, but there are three coiled springs, 2 are marked #4 35#, and the other one is marked #3 35#. The windows are double hung vinyl.

Thanks for posting. Your pivot shoe looks like our 15-199. This is compatible with our Series 160 Coil Springs. For your coil springs stamped 4, see our S160-4 springs that support 4.5 lbs of weight apiece. For the spring stamped 3, see our S160-3 spring, which supports 3.5 lbs of weight apiece. For a new coil support, see our 15-150T. Let us know if you have any questions.
