For the first generation N60 series Hilux Surf and export specification 4Runner introduced in 1983, Toyota, instead of developing an entirely new model, modified the existing Hilux (N50/N60/N70) with short-bed pickup body. The Hilux had undergone a major redesign in 1983 for the 1984 model year. Changes included the removal of the panel with integrated rear window from behind the front seats, the addition of rear seats, and a removable fiberglass canopy. The implementation was borrowed from both the second generation Ford Bronco, and the Chevrolet K5 Blazer, both short-bed trucks with removable fiberglass shells over the rear sections and having bench seats installed in the back. Like the Bronco and the Blazer, the Hilux Surf/4Runner also did not have a wall attached to the front section behind front seats as the regular Hilux did. In that sense, all three vehicles were more than simply conventional pickup trucks with a fiberglass shell included.
