The Pasture Green and Harvest Tan combinations were dropped later in 1946. The Harvard Red combinations were dropped in 1947 and replaced with Picket Gray with Harvard Red wheels, and Luzon Red with Universal Beige wheels. In 1948, these color combinations were also added: Emerald Green with Universal Beige wheels, Potomac Gray with Harvard Red or American Black wheels. For 1949, the Picket Gray, Michigan Yellow, and Normandy Blue combinations were dropped. Olive drab was also available for export models. On early CJ-2As, the front seats were covered in olive-drab vinyl. Around mid-1947, Slate Gray vinyl became available for certain color combinations. Later, Barcelona Red was added to the mix. A total of 214,760 CJ-2As were produced. Because of the use of military production parts on the earliest CJ-2As, and the many changes made during its early production, restorers and collectors refer to CJ-2As up to around serial no. 34,530 as "Very Early Civilian" and from mid-1946 to about mid-1947 as "Early Civilian". Only minor changes were made after the mid-1947 models. CJ-3A The Willys-Overland CJ-3A was introduced in 1949, and was in production until 1953, when replaced by the CJ-3B. It was powered by Willys' L-134 Go-Devil four-cylinder engine, with a T-90 transmission and Dana 18 transfer case, a Dana 25 front axle and Dana 41 or 44 rear axle. It featured a one-piece windshield with a vent, and wipers at the bottom. The CJ-3A had beefed-up suspension (10 leaf) to accommodate the various agricultural implements that were being built for the vehicle. Another difference was a shorter rear wheelwell (the wheelwell from the top front edge to the rear of the body is on the 3A compared to on the 2A) and moving the driver's seat rearward. As of 1951, a Farm Jeep and a Jeep Tractor version were offered; the latter was very bare-bones, for field use only, and featured a power takeoff. In total, 131,843 CJ-3As were produced before the series ended in 1953. About 550 of the CJ3-As were assembled by Mitsubishi as the J1/J2 in late 1952 and early 1953, exclusively for the Japanese police and forestry agency. The CJ-3A-derived military jeep was the Willys MC (or M38), and it began complementing the Ford and Willys World War II jeeps starting in 1949. CJ-4 The Willys-Overland CJ-4 or "X-151" was only built as an experimental concept in 1950 or 1951. It used the new
