While most foreign assemblers focused on the CJ-3B, Brazil received the CJ-5, instead. After having closed their market to imported cars in 1954, assembly of the "Willys Jeep Universal" (as it was known in Brazil) from CKD kits began in 1957. By 1958, production relied on locally sourced components, with the vehicles equipped with a 2.6 liter I6 engine (also used by Willys do Brasil for passenger cars). The Universals came with a three-speed manual transmission. The Brazilian-built vehicles are easily recognized by their squared-off rear wheel openings. In 1961, a long-wheelbase version, similar to the CJ-6, was added to the line. Called the "Willys Jeep 101", it shared the chassis of the local Rural, a redesigned Willys Jeep Station Wagon. Like the Brazilian-made CJ5s, the 101 has square rear-wheel openings. This version was introduced in 1961, but was not retained after Ford's takeover in the fall of 1967. On 9 October 1967, Ford do Brasil bought the Brazilian Willys subsidiary and took over the production of the CJ-5, the Willys Jeep Station Wagon-based "Rural", and its pick-up truck version. Ford kept the line with no modifications except for some Ford badges on the sides and on the tailgate. In 1976, Ford equipped the CJ-5 and the Rural with the locally built version of the 2.3-L OHC four-cylinder engine used in the Ford Pinto (also used in the Brazilian Maverick) and a four-speed manual transmission. This engine produced (SAE) at 5000 rpm. In 1980, the engine was modified to run on Neat ethanol fuel (E100); this option lasted until 1983, when Ford ended the production of the CJ-5 in Brazil. CJ-6 Introduced in 1953 as the M170 military version, the civilian CJ-6 made its debut in 1955 as a 1956 model. It was stretched version of the CJ-5 with a longer-wheelbase (101 in, 1955-1971 / 103.5 in, 1972–1981). The extended chassis allowed a variety of configurations, including adding a second row of seats. The M170 military version shared many of the features of the M38A1 (Military CJ-5), but had the passenger-door opening extended back to the rear wheel well. As in the CJ-5, the V6 and V8 engine choices appeared in 1965 and 1972. The U.S. Forest Service put of CJ-6 Jeeps into use. American sales ended after 1975, with the introduction of the CJ-7. A total of 50,172 were produced when the series went out of production in 1981.
