 History

1940: Jeep specification issued and prototypes built by Bantam, Willys-Overland and later Ford; see the Rifkind report.

1941-1945: Jeep MB, built by Willys-Overland and Ford, Willys 2.2L 4cyl side-valve engine.

1942: Ford GPA - Amphibious Jeep or Seep.

1945-1949: CJ-2A the first civilian Jeep.

1948-1953: CJ-3A.

1953-1964: CJ-3B one piece wind-screen, low wipers, and a high bonnet (hood) to clear the taller Hurricane F-head (ioev) motor.

1953: Kaiser take over Willys-Overland.

1955-1969: CJ-5 (a) one piece windscreen, high wipers.

1955-1969: CJ-6 (a) one piece windscreen, high wipers, 101" wheelbase.
1957-1965: FC-150, forward control, 81-inch wheelbase, pickup, was based on the CJ-5 (Corgi (UK) made a scale-model).
Also the FC-170, 103.5-inch wheelbase.

1970: American Motor Co. (AMC) take over Kaiser Jeep.

1970-1983: CJ-5 (b) low wipers. Dropped after 1983 m.y. because of safety issues.

1970-1976: CJ-6 (b), low wipers, 101" wheelbase. Many think that 100" is the best 4x4 wheelbase, 90" restricting load capacity and giving a choppy ride on-road, 110" giving poor manoeuvrability offroad. Nevertheless, the CJ-6 was not all that popular. Dropped in 1976 after the introduction of the popular CJ-7.

1976-1986: CJ-7, 93.4" wheelbase, soft-top or removable plastic hard-top.

1981-1985: CJ-10 has rectangular headlights and a 9-bar, 10-slot, grille.

1982-1986: Renault owned AMC Jeep (I remember this well because I worked for Jeep in those years as a parts counterman for a dealership & hated the way they set up their microfiche for parts. We also had to deal with the cars Renault made. It was a nightmare. - Kern L. N@poletano).

1987: Chrysler take over AMC (and Jeep).

1987: Wrangler YJ introduced (still leaf sprung). Made from 1986 on, it was derived from the Jeep CJ-7 with a wider chassis and track, a different nose and rectangular headlights. Many parts are common between the Wrangler and CJ-7. The early manual transmission was a Peugeot unit, not particularly strong and it is expensive to repair. The automatic tranmission is more robust.

1996: Wrangler TJ with coil springs and a return to round headlights!

1996: The coil-sprung Jeep Wrangler arrived in Australia.
