From Dodge Wiki
The Dodge Warlock, originally a concept vehicle and part of Dodge's late 1970s "adult toys" line, is a short wheelbase truck that was produced in limited production in 1976 and regular production from 1977 to 1979 under the Dodge name brand by the Chrysler Corporation, later known as DaimlerChrysler. They were available in 4x2 and 4x4 models and offered only in black, red, orange or green. Its main draw was that it was a factory customizable truck, also known as a "trick truck", and was designed to appeal to young 4x4 buyers. The 1979 model is different in that it has "Warlock II" printed on the tailgate.
