Got an '84 K30 with a crappy body. Its got a 12' flatbed on it, too. I have an '80 C20 with a good body and would like to swap it to the K30. Other than the tranny tunnel hump, what other issues? Will the steering column wiring hook up? Hydroboost hook up? I'm just concerned about the older style onto the newer style. Never have done a swap like this before.
