Centering the rear wheels

A spacer plate between the body and the front spring mount, and longer bolts. Plus you will need a longer driveshaft. This will also push your rear shackles back and change that geometry. Add a lowering block between the diffy and the leaf spring then you need to set up the pinion angle again.Thats if you use your stock springs. Now you can get a custom set of leafs made as well.
