Hello,

The pivot shoe shown in your photos is no longer available but we recommend the 15-177 to replace it. This shoe uses the same 1/2" width S152 coil springs. For coils stamped with 9, you'd need the S152-9 replacements. You can also find the parts used with this coil balance assembly under the related items section of our product pages. Thank you!
