The Sixty-Special was now a one model line, including only the Brougham sedan. It came with standard extras like Automotive Level Control; adjustable reading lights; Two-Way power adjustment Dual Comfort front seat and a padded vinyl top. New exterior styling was seen along with several new trim features. The windows were cut nearly into the roof in semi-limousine fashion and had softly rounded corners. Vertically angled rectangular coach lamps were a common option incorporated into the rear roof pillar. A broad rocker panel trim plate, with rear extension, was used. The Fleetwood name was block lettered on the front fenders, behind the wheel opening and on the righthand side of the rear deck lid. The new window styling included a wide pillar separating the front and rear door glass.
