Pivot shoes needed

Hello,

I can't be sure with the pivot shoe still installed but what I can make out reminds me of the 15-177. Note that this shoe measures 9/16" deep as shown below. If it's a match, these shoes are used with the 1/2" width S152 coil springs.

There should also be numbers stamped on the original coils that correspond to one of our strength options. We'll also relate a few videos on this page to help you through the replacement process. Thank you!
