Others will chime in, but it depends on the car. They're not all the same and there are differences in size between the Plymouth versions and the Chrysler.

They are not a direct interchange because there was some redesign. In 66 the subframe is bolted rigidly to the unibody. In 72 it is isolated with rubber mounts between them.
