Ford F-Series - 6th Gen (1973 to 1979)

The sixth generation Ford F-series was introduced in 1973. This version of the F-series continued to be built on the 1965 fourth generation's revised platform, but with significant modernization and refinements. Front disc brakes, increased cabin dimensions, full double wall bed construction, increased use of galvanized steel. The FE engine series was discontinued in 1976 after a nearly 20-year run, replaced by the more modern 335 & 385 series engines. In 1975, the F-150 was introduced in between the F-100 and the F-250 in order to avoid certain emission control restrictions. For 1978, square headlights replaced the previous models' round ones on higher trim package models, such as Lariat and Ranger, and in 1979 became standard equipment. Also for 1978, the Ford Bronco was redesigned into a variant of the F-series pickup. 1979 was the last year that the 460 engine was available in a half ton truck. 1979 would also be the last year for Sixth Generation production, with the Seventh Generation F-Series replacing it.
