Teaching my son to drive in a 51 Plymouth with a three on the tree.

Going to put in an A833OD I have on the shelf, that 3.09 first gear will really help him taking off, lol.

I don't pull hole shots or tow so the A833OD works fine for me, I probably have close to 200k miles on the two I have.

As for the aluminum case counter shaft hole issue, it can be bushed to fix that. I believe both Passon and Brewer's offer that service or did.
