Chrysler's rear wheel drive F platform was used from 1976 to 1980. It was replaced by the nearly identical Chrysler M platform. There were two wheelbases: 108.7 in for 2-door models, and 112.7 in for four-doors. As the market evolved, these would be marketed as mid-size and eventually take on full-sized nameplates such as Plymouth Fury for police and fleet applications.
