Father son 73 dart swinger restoration. (making it a 71 clone)

IMO the 1971 was the best year for the Dart.
It had the right grill, the right side markers, the right tail lights.

The 72 grill is good, too, but not as good as the 71, and the 72 and later side markers are sort of stuck onto the fenders, instead of flush like the 70 and 71.
I also like the 71's tail lights better than the 70's.

Just my opinion, of course, but, of the 70-76 Darts, I think the 71 is the best, followed closely by the 70 and 72. Then the early "A" body Darts, and then the 73-76 Darts.
