For the 12 bolt rear, I acquired an '85 Chevy truck rear clip with the plan to swap in the diff. After taking some careful measurements I found the frame was the same width as the '55 so I cut off the rear of the frame and welded in the '85.I mounted a gas tank in the rear and ran the exhaust. It would be driving by now except we spend winters in Mesa and the project is at my home in Oregon.
