Finally got this fixed.  On my way down through Georgia, just south of Atlanta is a Summit Racing Equipment store.  They had the rod ends.  Mild steel, rated at over 9,000 pounds.  They're a bit meatier than the originals, but fit just fine.  You'll have to discard the plastic bushings used on the original rod end, these have metal spherical inserts, rather than a large hole for a plastic bushing.  Be sure to use Locktite on the threads, as the cylinder rod can rotate, and over time loosen the rod ends.   
  
3/8-24 female thread for the cylinder rod, 3/8 hole for the top bolt.
