with the Dana 20 exist. Typically, they had 4.1-ratio, narrow-track axles. From 1976 trough 1980, the CJ-7 came equipped with a Dana 20 transfer case, Dana 30 front axle (27- or 31-spline), and a 29-spline AMC 20 rear axle, while in later years, Laredo packages added a tachometer, chrome bumpers, tow hooks, and interior upgrades including leather seats and clock. In 1980, the Laredo was first fitted with an AMC 20 rear axle until mid-1986, when it was equipped with a Dana 44, and all 1980 and newer CJ-7s came with the Dana 300 transfer case. The Canadian Army took delivery of 195 militarized versions of the CJ-7 in 1985. These were put into service as a stop-gap measure between the retirement of the M38A1 and the introduction of the Bombardier Iltis. They were codified by the Canadian Forces with the Equipment Configuration Code number 121526. The CJ-7 continues to be used in the sport of mud racing, with either the stock body or a fiberglass replica. CJ-7 has been successfully and widely used as a favorite for rock crawling, through simple and complex modification. These last Jeeps produced were also highlighted with a factory dash plaque that read, "Last of a Great Breed - This collectors-edition CJ ends an era that began with the legendary Jeep of World War II". During 11 years of production, the CJ-7 had various common trim packages: 1976-1986 Renegade (2.4D L6-2.5-4.2-5.0 AMC 304 V8) 1976-1980 Golden Eagle (5.0 AMC 304 V8) 1980 Golden Hawk (5.0 AMC 304 V8) 1980-1986 Laredo (2.4D-4.2 I6) Jeep also produced two special edition CJ-7 packages: 1982-1983 Limited (2,500 units were built as a limited-production luxury model; 4.2 L I6 with T5 or automatic transmissions) 1982 Jamboree Commemorative Edition (630 numbered units built for the 30th anniversary of the Rubicon Trail; 4.2L). with only 630 units produced (560 Topaz Gold Metallic and 70 Olympic White), the CJ-7 Jamboree is the rarest CJ-7 ever built and one of the rarest Jeeps of all time. The Jamboree is in the same production rarity class as the 1971 CJ-5 Renegade-II. It is the most heavily optioned CJ ever built; it was the Rubicon of its day. All units were uniquely numbered via a dash plaque; it is the only AMC Jeep to have been numbered. Engines AMC I4 GM Iron Duke I4 AMC I6 AMC I6 , AMC V8 , Isuzu Diesel C240
