I stumbled across a 46 dump that has something that looks like a second transmission about halfway back. Everything looks factory but who knows, someone might have gotten creative 50 years ago. I will say this it looks cool. Could this be an early 2 speed rear end? Speaking of cool, I saw an interesting steering wheel. It is suppose to be a factory deal. It has a dial built in the left post that you grip with one hand, works on the premise of the knob without the dangerous knuckle busting knob. How common are these things? I been to a lot of car shows, I've never seen one, this guy had five!
