Cluster bearing solution?

[nkaminar]

In October I visited Sammy at Arizona A's. He sells new and used parts for Model A's and T's and has restored many cars and repaired cars for people. I asked him about the modern bearings for the transmissions. He said that the problem is not the bearings but the way they are installed. He said that they are often damaged by installing the parts while the transmissions are horizontal and recommended installing the parts while the transmissions are vertical, and done carefully. One man's opinion, but from someone who I regard as an authority.
