C/K is the name commonly used for Chevrolet (and GMC’s) full-size pickup truck line from 1960 until 1999 in the United States — C indicated two-wheel drive and K four-wheel drive. In 1960, C/K trucks were available in smooth “Fleetside” or fendered “Stepside” versions. (Called “Wideside” and “Fenderside on GMCs.) There’s a little bit if everything at Dan’s Garage.
