1964: Jeep M-676, M-677, M-678, M-679
The Jeep Forward Control pickups debuted for 1957 in a short-wheelbase half-ton FC-150 and a longwheelbase one-ton FC-170, both four-wheel-drive. They were innovative cab-over trucks but didn’t set the light truck market afire. Sales were never better than adequate and had begun to taper off in the early ’60s. About that time, while trying to land a big contract for a new light tactical military vehicle, Jeep learned the Marine Corps was looking for a non-tactical all-wheeldrive rig with diesel power. They proposed a militarized version of the Forward Control, designed and built it, and got a contract. Starting in 1963 they began building the M-series FCS powered by Cerlist 3-cylinder, 2-stroke, loop-scavenged diesels that made 85 hp from 170 cubic inches. They were built in four configurations, the M676 pickup, M677 four-door pickup, M678 and M679 Ambulance, and around 400 units of all types were known to have been built.
