lightest a-body??

Remember, Darts are 3 inches longer than Valiants and Barracudas, so they will always be heavier. Barracuda fastbacks have the heavy glass (especially the early ones), so they will be heavier than the contemporary Valiant as well. And 63-66 will be much lighter than 67-up for all body styles. 4 doors are heavier than 2 doors. So the winner is, early Valiant 2-dr.
