The first generation of Broncos, considered ‘Early Broncos’ were produced from 1966-1977. The idea was to get the short, compact build of a car with a more truck-like suspension and design. They wanted to produce a utilitarian, simple and sporty vehicle, ready for adventure. With little comfort options available, they did offer a variety of accessories for Early Broncos including a snowplow, a winch, and a posthole digger—options that further embodied the rugged personality of this do-it-all vehicle. The early base Broncos were sold as roadster-types, without a roof or doors. All Early Broncos were 4-wheel drive and came with a Dana Corporation Model 20 transfer case and manual locking hubs. In all its years, the Early Ford Bronco came from the factory with a 9-inch rear end. From 1966-1971, the Early Bronco sported a Dana 30 differential. In late 1971, Ford changed to the much stronger Dana 44 model front end standard. Designed by Paul G Axelrad, McKinley Thompson Jr., and their team, the Early Broncos were created with a focus on simplicity and economy, in order to compete fairly with the Jeep and International Harvester models on the market. The axles and brakes were roughly taken from the Ford F100 4×4 trucks with some minor alterations allowing the use of coil springs giving the Early Bronco a 34-foot turning radius and longer wheel travel.
