1990 Ford Bronco “none”

The fourth-generation Ford Bronco ran from 1987 through 1991 on the redesigned F-series "Bricknose" body, named for the flush, aerodynamic front clip with flush headlamps that replaced the boxy Bullnose face. For 1987 Ford gave the 4.9L (300) inline-six electronic fuel injection and added rear-wheel anti-lock brakes (RABS) as standard equipment, two of the generation's defining mechanical changes; the 5.0L (302) V8 carried over its existing electronic (throttle-body) fuel injection from the third generation. The optional 5.8L (351 Windsor) V8 stayed carbureted for 1987 and received EFI for the 1988 model year. The engine roster carried the 4.9L (300 cubic inch) inline-six as the base unit, with the 5.0L (302) and 5.8L (351 Windsor) V8s optional. The Bronco kept its full-size two-door wagon body with a removable fiberglass rear hardtop over a 104.7-inch wheelbase, sharing its structure with the F-150 ahead of the B-pillar. Twin-Traction Beam (TTB) independent front suspension carried over from the third generation, as did the basic engine family, so the 1987 changes were fuel injection, braking, and styling rather than a new chassis. The Mazda-built M5OD five-speed overdrive manual replaced the older four-speed manual around 1988, and the biggest later mechanical addition was the E4OD four-speed overdrive automatic for 1990. The base trim was called Custom for 1987 and was renamed XL for 1988; above it sat the better-equipped XLT and the upscale Eddie Bauer.
