To fight corrosion, Ford increased its use of galvanized sheet metal, zinc coated steel, and zinc-rich primer.

[3] To increase safety, the fuel tank was moved out of the cab (to below the pickup bed[3]), creating a storage area behind the bench seat.

In 1975 (1976 model year), this familiar "split-grille" design was given a slight facelift to feature black accents around the headlights and a refined overall appearance.

[4] 1977 models received a redesign of exterior trim, with the cowl insignias made smaller and moved near the windshield.

For 1978, the split grille gave way to a larger single-piece item which no longer incorporated the headlamps, the turn signals, or the ford callout.

[citation needed] For 1979, all models used the rectangular headlamps, with bezels available in either black or chrome to match the aluminum grille frame.

For 1974, the Explorer package was offered on the F-100, F-250, and F-350 (and the Ranchero and Bronco), consisting of color-keyed exterior and interior trim, badging, and wheelcovers.

[6] The 1977-1979 "Free Wheeling" package (offered on the Custom and non-Lariat Rangers, along with the Bronco and Econoline), consisted of multi-colored tape stripes, silver or black interior, white-letter tires, and optional alloy wheels, bed-mounted roll bar, and bumper-mounted push bar.

[7] Ford Australia assembled right-hand drive sixth generation F-Series that were fitted with a lineup of locally sourced engines.

The 250CID Straight-6 was upgraded with a new crossflow head and rebadged as the 4.1 litre, increasing power and lowering emissions to meet new legislation being introduced in Australia.

To compete directly against the Chevrolet K5 Blazer and the Dodge RamCharger, the Bronco grew in size, adopting a shortened F-100 4x4 chassis.

While continuing the two-door wagon bodystyle of the previous generation (the most popular version), the 1978 Bronco adopted a half-cab/hardtop design (also used by the Blazer); the configuration was used through the 1996 model year.

Along with greater sales potential (the first-generation Bronco competed nearly exclusively against the International Scout), the redesign of the Bronco allowed for product commonality with the Ford F-100 (and the F-150 that eventually replaced it); for the next two decades, the two model lines would share nearly all exterior body panels from the front doors forward, many interior and trim panels, and would also have powertrain commonality.

Produced without bodywork aft of the firewall, the Ford B-series was a cowled chassis designed to be mated with bus bodies (primarily school buses).

The highboy design configuration saw its origins as American manufacturers introduced factory-produced 4x4 pickup trucks in the late 1950s.

The location of the transfer case precluded the fitment of a second fuel tank and the higher ride height would have decreased rear-seat access for the two-door SuperCab.

At the 2021 SEMA show in Las Vegas, Ford unveiled the F-100 Eluminator one-off concept truck, an electromod restoration of a 1978 F-100 repowered with the electric vehicle drivetrain and front and rear suspension subframes taken from the Mustang Mach-E GT Performance Edition.

[20] Ford contributed front and rear sub-frames, which were already fitted with electric traction motors, and a battery pack from the Mach-E production line.

Roadster Shop built a custom ladder frame to support the vintage body, attach the subframes, and carry the battery underneath the cab and bed.

[23] The Eluminator crate motor has an output of 281 hp (210 kW) and 317 lb⋅ft (430 N⋅m) of torque, with a total weight of 205 lb (93 kg).

[25][26] At the time of release, Ford Performance announced they also were planning to develop battery systems, controllers, and traction inverters to make a complete drop-in EV drivetrain replacement available commercially for interested parties.

[19] The F-100 Eluminator is fitted with two traction motors, one each for the front and rear axles, with a combined output of 480 hp (360 kW) and 634 lb⋅ft (860 N⋅m) of torque.
