Thelong wheelbase Fleetwoods were still called Seventy-Fives, although a new numerical series designation was in official use. Production models again were a nine-passenger sedan and Imperial sedan-limousine with auxiliary jump seats. Fleetwood lettering appeared on the rear deck lid trim strip. Single side trim moldings extended from the front wheel housing to the rear of the car. Standard equipment included all items found on the Sixty Special Fleetwood line.
