Hey there, thanks for reaching out! Your pivot shoe resembles our 15-228, 17/32" thick pivot shoe. Compare the dimensions shown on the diagram below to your existing shoe to confirm that this is the right fit.

Dimensions for 15-228

The coil springs compatible with this shoe are the 1/2" thick, Series 160 coil springs. Given that yours is stamped with a 9, I suggest the S160-9. The compatible cover would be 15-150S.

Look of each of the recommended hardware and compare it to your originals to determine if these are the right replacements. Let me know if any of them are not a match.
