71-72 charger diff in A bodie ?
If you use a Sawzall and cut the quarter panels, you can fit the axle with any times that you want.
The 68-70 B body axle is already pretty wide for a Valiant or Dart.
The black Dart has a 68 Coronet 8 3/4" axle and 14 x 5.5 Rallye wheels.
The 71-72 is several inches wider and will NOT fit without cutting.
