For the 1963 model year, the wheelbase was increased to 119 inches (3,023 mm) and the car received new sheet metal. The Dart name was reassigned to Dodge's line of compact cars that had previously been known as the Dodge Lancer. Positioned below the Polara were the plain 440 and 330. The 1964 models received a revised front end and new tail lamps to distinguish them from the 1963 cars. Rear end treatment took its inspiration from the Chevrolet Impala, the Polara models now featuring six small, square-shaped taillights (three on each side) surrounded by an attractive bright trim panel. Lesser big Dodges featured only four taillights (two on each side) and lacked the bright trim panel. A sensational new "C" pillar for the hardtop coupes, combined with the more attractive front and rear end styling, made the '64s look totally new (and longer/ lower/wider as well), resulting in a significant increase of sales over 1963.
