K member question

Im curious. How does one pass a Dart off as a Demon? Since the last year of the Demon was 72, and there were no sportback Darts, until 73.And no 73up Demons, only DartSports. One would have to take a 73up DartSport and bolt all the 71/72 Demon front end onto it, and then do a heck of a job on the tail,and finally, swap the vintag and the other non-agreeing stamped sheetmetal.Thats an aweful lot of work. What am I missing? Do people really do that?
