I just wanted to add pics of the coil as well. I did find a number 5 stamped on the coil.

Sure thing! I recommend our 15-140 pivot shoe, which is compatible with the Series 150 spring. Since yours is stamped with "5" I would go with the S150-5.

If you also need new covers, see our 15-143, 15-144, and 15-145 drum. 

This hardware all looks very similar to the parts in your photos, but review our information and let me know if you agree.
