Jim did you find the spring kits?
I just did mine (my shoes look way different then yours) and cleaned up and re-used the originals. All seemed to be in good shape. The shoes weren't bad either but since I had to replace the oil soaked rears, I wanted all 4 to be the same material.
FYI-I sent mine to Brake Materials and Parts in Indiana brakematerialsandparts.webs.com
Talk to Scott. Great to deal with.
