Hello,

Your pivot shoe appears to be an older version of our 15-180, which is designed to use the Series 190 coil springs. Review the specifications shown on our product pages to confirm they match up to yours. Thanks for posting!

It's tough to tell but it looks like the coil in your photo may be stamped with an 8. If so, you would use the S190-840 replacement coils, which support 8 pounds each.
