The Chevy K5 Blazer is a full-size sport-utility vehicle that was built by GM and introduced to the Chevrolet line for the 1969 model year. In 1970, GMC introduced its own model of the truck, called the Jimmy. Both were short-wheelbase trucks and available with either rear- or four-wheel drive. The K5 Blazer and Jimmy had “full convertible” removable tops until 1975, but in 1976, GM introduced a half-cab design that was less prone to leaks and slightly safer in a roll-over. These half cabs had the removable top begin a few inches behind the driver/passenger doors and run back to the tailgate. The K5 Blazer was replaced by the Tahoe in 1995 and the Jimmy variant was replaced by the Yukon in 1991.
