Well, 67 was the first year of that body style of Dart. That lasted 67 - 69, then in 70 they changed the nose and rear, but the body style was the same. The taillights were now in the bumper, and the nose had a smaller bumper and plastic grille. 70 - 72 had the flat front end, 73 was pointy but still held the tail lights in the bumper. Then 74 - 76 was pointy with tail lights above the bumper. But the beginning of the A body for Darts was 63. 62 was a B body.
