Minor restyling's were made for the 1973 Plymouth Duster, including a new hood and grille, and the taillights that were also changed, as bumpers were replaced with heavier new bumpers that complied with the new mandated Federal 5 mph safety regulations. Exciting enough,the new Space Duster, was added to the model line-up and featured a fold down rear seat and folding trunk separator offered more than 50 cubic feet of cargo space.
