I have a '58 1 ton NAPCO 4x4 with single rear wheels. It was known as "Rescue 8" for the Croton Falls fire department in New York; they bought it new from Brady-Stannard Chevrolet in June of 1958. It has a factory PTO winch and 21,000 original miles. It has some rust issues, but runs like a top. I'll have to send in some pic's for the gallery one of these days.
