Changing a 74 Dart Swinger to look like a 71-72 Dart Swinger

There was a guy on moparts.com that has done it. I do not remember his "name", but his wife's is dustergirl340. Seems to me he had to cut off the tail end of the newer car and weld on the tail end of the older car. Looked good to me when I saw it during a Woodward DreamCruise a few years ago.
