The 1977 model year
Overview
The final first-generation Bronco retained its standard 302-cubic-inch V8 and the choice of synchronized three-speed manual or SelectShift Cruise-O-Matic automatic. Ford presented the Bronco and Sport Bronco with Ranger as an optional package, all using the enclosed two-door 92-inch-wheelbase body.
