If I'm following correctly, it sounds like you need a replacement coil balance. If so, can you show me a picture of the pivot shoe to which your spring connects? That would be a huge help.

Your exact balance system has been discontinued by the manufacturer, but you can use our 15-140 shoe and S150-8 coil springs as a replacement. The other fittings are the same, but see our 15-143, 15-and 15-145 if you need them.
