Hi i am using early 60 C body on my 67 Dart 383 fits pretty good the drivers side i want change as i want to add power stering. Just this week i bought a rebuilt 440 and part of the deal included two driverside manifolds 1#2951865 off 70-71 B-C body and a 2806974 driver side off 440 magnum i will know soon what one will work best on a 67 dart 383
