Oh no!!!
I just drove a 1967 Dodge M37 Power Wagon from TN. to TX... Nice ride, and 10mpg out of the old gas flathead! We can address the ethics of your genetic experimentation later, but how do you like the 4x4 56?
I will check out the build thread, more pics later today. We are trying to get the bed off to see how bad the frame is bent...
