In the early years after World War II, a small vendor in Minnesota stepped up to meet the demand for four-wheel drive light trucks and transformed 2WD GM trucks into 4WD in only hours. Can you name this one?

Napco, or Northwestern Auto Parts Company, developed a Powr-Pak 4x4 Conversion kit, which helped transform a 2x2 GMC truck into a four-wheel drive in only a few hours. These transformations date from 1947, however in 1956, the Powr Pak was offered by GMC as a factory-installed option.
