Re: 87 Chevy Crew Cab 4x4 Converion/Cummins swap

Never did it the other way around, but essentially the same I suppose. It certainly helped to have the whole frame to take my measurements from but really not necessary. Probably the worst part will be sourcing the different spring hangers for the swap. For the rear you can shackle flip, which takes care of the rear most. You need to find the front rear hangers. Basically just strike a center line then re attach them. For the front there are a few companies that make the b52 hangers to do the longer spring swap in the front, then you can buy the shackle bushing and shackles from DIy4x or offroad design. The engine stands are the tricky part when you keep stock driveline because everything has to line up! For the cummins it was all custom anyways so that part wasn't 'as crucial'
