Doctor Diff 1/2 offset spring hangers are back !
As 72bluNblu mentioned, bump in outer wheelhouse is a main point of interference. I had an A body 8.25 under my Duster at first. With 15x8, 4.5 BS and 275/60 , I had plenty of room to the outside but was very close to the spring and inner wheelhouse and would sometimes rub on corners. I got an 8.75 rear and narrowed it to stock A body width (52&5/8), DD BBP axles for A body along with the DD offset hangers. Now I have plenty of room to wheelhouse and springs but rub the outside on hard bumps. If I were to do it over, I would cut the housing a little narrower , maybe 52.0. My car has a rake but sits down over the tires.
