Yep...I just located a couple of NOS inner bearings via Ebay that match the updated factory Hyatt numbers (11410 Z) for about $25 bucks apiece. The outers that were on my rig were both Timkins that are still available...with the catch that NAPA (and the only other vendors I've found that have them) want $250 bucks apiece for the suckers! They are 15574 A's.
If anyone has come across valid replacements that are less...please...let me know.
PS...I did just come across them at WBC Industrial. They get $674.20 each. ??????
