The only place that I ever found that carried the bearing retainers as part of a kit was CarQuest. There supplier has now discontinued them. They have one left side (no adjusting side) in St. Louis. Every one is using green bearings now. I just bought Mosuer axles set up for tappered bearings for one of my cars and now I find out there not available any more. Afraid to use green bearings as the car is set up to corner hard and will be driven that way. I'll get a set of them off some used axles.

Dr. Diff here on Mopars has used ones. mailto:doctordiff@gmail.com
