Re: Mack M75SX
That's a nice 1 ton dually you have there, Steve. I like the direction your Mack is headed too. I have to echo what the others said. Keep the axles. They are really nice. I'd suggest you just find yourself one big and brawny gearmotor to use as the transmission. We could calculate a good ratio for you, based on tire size, motor selection, and the voltage you want to run. As long as we know the motor's RPM per volt, or Kv rating, and an idea of how fast you want this thing to go.
