Yeah- I think it a CJ-6. See the fourth sentence below. Looks like a longer wheelbase.
The CJ-6 was a stretched version of the CJ-5 with a 20 in (508 mm) longer-wheelbase (101 in, 1955-1971 / 103.5 in, 1972–1981).[70] The extended chassis allowed a variety of configurations, including adding a second row of seats. Introduced in 1953 as the M170 military version, the civilian CJ-6 made its debut in 1955 as a 1956 model. 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.[71] The U.S. Forest Service put a number of CJ-6 Jeeps into use. American sales ended after 1975, with the introduction of the CJ-7. Just 50,172 had been made when the series went out of production completely in 1981.[40] Just as in the CJ-5, the V6 and V8 engine choices appeared in 1965 and 1972.
