I got a call from the same fellow with the 1 ton with 4BT. He is looking for a pair of long running boards.

I asked a few questions about the conversion.
I think he is stil using the same rear, I am sure a 3.54 or faster rear would help it considerably on the speed, noise, vibration, and fuel mileage.
He also said that he bought the engine new from cummins for around 4,000 a few years ago. He has also done a Diamond T with the same engine, I have seen that one at shows, however he no longer owns it.
