Pivot shoe

Thanks for posting. Without seeing it out of the window I can't be 100% of your pivot shoe's identity, but I believe it might be an older version that can be replaced with our 15-177. This shoe works with Series 152 Coil Balances. If your old coil springs are undamaged you'd be fine reusing them; but check for wear and tear when replacing your pivot shoes. Let me know if you have further questions.
