This has been asked before, but that is not the point. If you are good at fabrication and metal work, I would say throw the 1985 front axle and all the entrails onto the 1986 frame. But if you are not so good with metal work, welding, and fabrication and have a lot of time on your hands and patience I would say body swap. In the long run, both will take *about* the same amount of time, depending on how fast you work, and if time is a factor in your decision. It is your decision, after all it is your build. Whatever you are best at, go for it.
