Your S160-3 coil balance and 15-111 pivot shoe are identical to the appearance and specifications of my damaged parts except they are 1.25 inches wide. Mine are 1.0 inch wide. Do you carry parts in this width and if not do you know where they can be found?

1" is very unusual for this kind of balance system. Would you be able to show us a couple pictures of your shoe and spring removed from the window? That may help us find something closer.
