I used the offset kit fron dr Diff and welded a larger diameter tube in factory holder to accept larger bushings. Was this what your doing or are you going to center of the frame?
That's an offset kit. He's doing a spring relocation, so the 3" move to the frame rails. Just FYI, you can use Energy suspension 2-2117G bushings for A-body shackles. They have the correct 1/2' bolt diameter and larger 1" OD for aftermarket, SS and mopar performance springs.
