For anyone needing the information, here is a list of bearings and races needed to rebuild the rear end. I went to an industrial supply company and got quality USA made bearings. Some of these are available from Auto Zone in a China brand but I spent the extra money on quality brands. Watch out for the LM603015, Those are very expensive. After I paid $75 each for them I found that Summit offers them in this brand for $50 each.
LM603049 need 2
LM603015 need 2
M88038 need 1
M88010 need 1
M802048 need 1
M802011 need 1
