Series 75 Fleetwood models were also facelifted to conform to the minor changes seen in other lines. Jump seats were used in both the seven-passenger sedan and Imperial limousine. Hydra-Matic drive was optional and hydraulic window lifts were standard. Business sedans were built in limited numbers on a special order basis.
