I've got a '65 heavy duty panel van. I have some unconventional ideas for customization, and one was seeing if anybody has put a driven front axle on a first-gen? I was looking at using maybe an np203 transfer case for full-time 4wd. Pretty sure from some simple research that some steering linkages will have to be fabricated, but as just a solid beam, is there a reason it can't be swapped with a driven axle?
