If I were to do it I would,Disconnect the leaf springs. Cut the front and back mounts off. Then take the back mounts and center them at the front of the frame, and weld it. Then take the front shackle mounts and attach the springs to them and weld them to the frame.If you look close to where he welded the back shackle mount, in the picture you can see just behind it is where the previous mount was. Just my 2 cents.
