Early b body in an a body

Ok so with the offset hangers you will have to move the perches in further right? Say it's a 1" offset you will have to move the perch in one more inch. Thanks.

Yes, but it's not quite 1". If you decide to go this route there are two manufacturers of offset hangers; Cass (Dr. Diff) makes some really cool heavy-duty offset brackets http://www.doctordiff.com/, here's an Ebay listing for them: http://www.ebay.com/itm/Mopar-A-bod...2959712?pt=Motors_Car_Truck_Parts_Accessories, or Mopar Performance brand purchased through a seller like Mancini Racing: http://chucker54.stores.yahoo.net/manofshacand1.html
