Not true. Having done this swap, I can tell you the 70-73 quarter panels are different than the 74-76. Marker light holes in the wrong location, quarter panel for the 74-76 are a full 1.5 inches shorter than the 70-73. The angle of the rear of the quarter where it attaches to the tail panel is also different. The rear trunk floor on a 74-76 dart must be extended approximately 1.50- 1.75 inches behind the spare tire well to the rear tail panel. There's pictures in my build thread.
