F800 and the F1000 between 1968 - 1978. This model retained the same body shape for its 10 year production life, the later models fitted with inertia-reel seat belts, and separate front parking indicator lights. The rear engine Bongos had a full chassis (shared with the Mazda 1000, using the same engine mounted to a transaxle at the rear) and were very strong and due to the low gearing, able to carry one ton. Due to rust and poor maintenance, the rear engined Bongos are now few and far between. Exact numbers are not known, but a world-wide register is currently being constructed to track all remaining examples. The next Bongo van appeared in 1978. It was a mid-engine rear wheel drive vehicle. Ford sold this version of the van as the Ford Econovan, while Mazda sold it for export as the E1300, E1400, and E1600, depending on engine size.
