coil balance parts

Question

I have three broken balances to replace. One is a  single coil balance for a regular house window, and two are double coil balances for a larger window. The balance for the larger window is pictured in one of the photos. I couldn't remove it because the cutout was not large enough; I suppose I will have to cut it as described in one of your videos. The double coil balance looks like it is 3 1/8 in. long and about 1 /12 in. wide Dimensions for the single coil balance is shown in the photo which I hope helps.

This looks like the 15-192, which uses the Series 170 and Series 171 Coil Balances. The video below explains more. Note however that if this was a Simonton window, you may have an older version of this shoe with a slightly different metal cam. You will need to swap out the old cam with the new one.
