I bought a set of used 3/4" offset spring hangars for an a body . the guy said he didn`t like the way they fit his car.(got them dirt cheap, 35 plus shipping if I remember right)) the bolts were offset enoughe to get 3/4 w/ the existing hole in the frame elongated just enough to get the front hangar in, it changed mine just 1/2 hair shy of 3/4", the back ones were offset exactly 3/4, and I made the pads exactly 3/4, worked like a charm .
really didn`t help that much on tire clearance tho! ----bob
