You're showing me an old version of the 15-180 shoe, plus a Series 190 spring. I've placed some other related parts in a list on this webpage, as well, so take a look. I think you can use these to repair your balance system.

Coil springs are marked with a number at the end of the spring, and the number tells you which spring to order as a replacement.
