Ford F-Series (fifth generation)

• 1967: Introduction of fifth-generation F-Series in 1966 for the 1967 model year. Cab is 3 inches (7.6 cm) wider than predecessor and frame is heavier. Grille, exterior trim, interior cab fittings and engine choices are unique to this year. Trim levels are "Base", "Custom Cab", and "Ranger".
• 1968: As federal regulations required all automotive manufacturers to install side marker reflectors or lights, Ford redesigned the hood emblems to incorporate reflectors as well as added reflectors to the rear of the bed. Interior fittings changed due to new safety standards. New versions of the FE-Series engine added (360 truck and 390). First year of factory-installed air conditioning (air conditioning was installed by the dealer before 1968).
• 1969: New grille design, new 302 Windsor V8 engine option.

1971 F-250 Camper Special

After 1968, Ford discontinued the "Low GVWR" versions. Still available was the Camper Special option (heavy duty cooling, camper pre-wiring, and larger alternator) along with the new Explorer Special (a limited edition trim and option package that combined many of the "Ranger" trim pieces with a lower overall price), Contractor's Special (including a behind the seat toolbox and 3/4 ton (F-250) suspension), Farm and Ranch Special (extra toolboxes and heavy springs), and Heavy-Duty Special (extra hauling abilities). These special models had various levels of options factory installed to appeal to different target groups.[5][6]

The fifth-generation F-Series was introduced in Argentina in 1968, where it remained in production until circa 1973. Was made in the following models: F-100,[7] F-350[8] the medium duty truck F-600[9] and the F-700.[10] It remained almost on par with the US range, without major chronological mismatches, in terms of the renewal of the range. The local make Igarreta, provides some interesting versions with custom configurations for private companies and also for the Argentine State.

Late Brazilian-built Ford F-1000, this one a double-cab conversion ("Galáxia")

The fifth-generation F-Series was introduced in Brazil in 1972, where it remained in production until circa 1992.[11] It received a series of changes and updates over the two decades of production, eventually being fitted with a 4-cylinder MWM 3.9 liter Diesel engine available in both naturally-aspirated (D229-4) and turbocharged versions (TD229-4) in a local equivalent to the F-250 badged as F-1000, also available with a 6-cylinder 3.4 liter engine both in gasoline and dedicated-ethanol versions, while the F-100 retained the gasoline-powered Y-Block 272 V8 and the Georgia OHC 2.3L 4-cyl in both gasoline and dedicated-ethanol versions. It was the last Ford truck manufactured in the Ipiranga plant which closed soon after the truck's discontinuation. Brazilian F-100 and F-1000 were only available with a single cab and 2-wheel drive, but a number of local specialists custom-built double cabs, and Engesa provided an aftermarket 4-wheel drive conversion.

In Canada the Explorer Special was a trim level that sat between the base model truck and Custom Cab. It used the Custom Cab trim and grill but didn't include things like a radio.

The heavier duty models (F-500 and up) continued to be built on the fifth generation chassis even after the lighter-duty models were replaced. In 1977, the lightest F-500 was discontinued, leaving the F-600 as the lightest of the medium-duties. It was built until the introduction of the seventh generation F-series in late 1979.
