The Sixty Special was very distinctive and rich-looking this year. Broad ribbed stainless steel fairings decorated the entire rear quarter panel, below the conical flare. Even the fender skirts featured this type of trim, which extended fully forward along the body sills. Sixty Special scripts appeared on the sides of the tailfins and a Fleetwood script nameplate adorned the rear deck lid. Standard equipment included Hydra-Matic, power brakes, power steering, power windows, and fore-and-aft power front seat.
NOTE: The commercial chassis features a 156 inch wheelbase and was provided to professional car makers for construction of funeral cars and ambulances, etc.
