Never very popular in the United States, most CJ-6 models were sold to Sweden and South America. It was also assembled in South Africa, by Volkswagen's local subsidiary, and in Israel by Kaiser in Haifa and later by Israel automobile industries in Nazareth. CJ-5A and CJ-6A From 1964 to 1968, Kaiser elevated the Tuxedo Park from just a trim package to a separate model for the CJ-5A and CJ-6A. A Tuxedo Park Mark IV is signified by a different prefix from a normal CJ-5 with a VIN prefix of 8322 and a CJ6a is 8422, while a normal CJ-5 VIN prefix is 8305 from 1964 to 1971. CJ-7 The Jeep CJ-7 featured a wheelbase 10 inches longer than that of the CJ-5, with its curved side entry cutouts partially squared up to accommodate hinged doors. The other main difference between CJ-5 and CJ-7 was to the chassis, which consisted of two parallel longitudinal main c-section rails. To help improve vehicle handling and stability, the rear section of the chassis stepped out to allow the springs and shock absorbers to be mounted closer to the outside of the body. It was introduced for the 1976 model year, with a total of 379,299 built during eleven years of production. Transmission options included the standard part-time two-speed transfer case, automatic, and an optional new automatic all-wheel drive system called Quadra-Trac. Other features included an optional molded hardtop and steel doors. The CJ-7 was also available in Renegade and Laredo models. Distinguished by their different body decals, the Laredo model featured highback leather bucket seats, a tilting steering wheel, and a chrome package that included the bumpers, front grill cover, and side mirrors. An optional Trak-Lok rear differential was available, too. The reports of the CJ-7 were different in each type of engine: the diesel was mated to the 4.10 ratio axle (in both Renegade and Laredo), while the 258 cubic-inch straight six and 150 cubic-inch four-cylinder used 3.73 and AMC V8 304-powered models (produced 1976–1981, which became part of the Golden Eagle version) used the 3.55 ratio axles. A diesel-powered version was made in the Ohio factory for export only. The engines were provided by General Motors, the owners of Isuzu Motor Cars. Production of this diesel version was between 1980 and 1982. This model had the Isuzu C240 engine, T176 transmission, and Dana 300 transfer case, although reports of some being produced
