I just rebuilt the original hubs on my 1970 K/5 Blazer a few weeks ago. I was fortunate to locate a pair of NOS clutch ring assemblies on EBAY.
The inner clutch ring is 3937062 or Spicer 23347X. A search on EBAY will have a few pop up brand new.
The outer gear is 3937061 or Spicer 23346X, and is still available here:
