Coil replacement

Thanks for posting. The pivot shoe looks like an older version of the 15-177. This setup works with Series 152 Coil Balances. The stamp 'E' suggests you need a 5 pound spring, in which case you'd need the S152-5 5 pound spring. You only need to replace what is broken with these coil balance systems, so if the shoe is fine, you can reuse it. You can also reuse the old coil housing--but otherwise, see the 15-143, 15-144, and 15-145. These newer style parts 'sandwich' around each individual coil. Let us know if you have further questions.
