So I want to lengthen my 51's 6400 frame by 3 feet, and also move my rear springs inboard.
looking to see if any one has pictures on what they used and how the lengthened their frame.
As for the inboard swap on the springs the dana80 rear I have for the truck is a bit narrower than the old two speed rearend, my plan was to move the springs in and then put airbags under the frame to the rear to do most of load work.
suggestions please
