Thought I'd close this thread. After a bit of research, I found that Briggs & Stratton still manufacture all the components need for this machine. I found the 2) Bearing Retainer part# O71043MA @ eReplacementParts.com for $8.20 ea. They had the bearing but I had already found and purchased them from TSC, Hillman part# 838682 for $2.85 ea. So for less then $25.00, I got my front drive up and running. I say it's working as good as new but since I purchased the mower used, I haven't a clue what new was like.
