The C10, C20, C30, K10, K20 steering columns are interchangeable...3-speed to 3-speed, 4-speed to 4-speed, automatic to automatic. You will need a 16 pt x 7/16" socket (rag joint bolt), tie rod fork (rag joint @ steering box), steering wheel puller, 3/4" socket (steering wheel nut), phillips screw driver, 1/2" socket, 7/16" socket, rachet, 5/16" nut driver and maybe a few other small hand tools, depending on how the column was installed. The column assembly, minus the steering wheel, will pull through the opening in the firewall and out through the cab, in one piece.
