I don't have any experience with those rockwells but I had a 74 with a 203 case and it made the same kind of noise but it sounded like it was coming from the axle, still changed out the 203 for the original 205 and problem fixed. Maybe you could put the front up on jack stands, disconnect the rear drive shaft and then run it in 4wd, and see if you can get a better idea.
