Thanks for writing in! Your coil balance assembly is no longer made, unfortunately. The good news is we do sell more modern parts that may be worth considering as a replacement. Although, I cannot make any guarantees that they will work so you'll have to compare the dimensions to your existing hardware.

Take a look at the 15-228 pivot shoe along with the 1/2" thick, Series 160 coil spring. To confirm the correct coil springs, you'll need to check your existing coils for any stamps/markings. If there are non, you'll need to obtain the exact weight of your window and divide it by the total number of coils in the window.

These use the 15-150S coil single support.
