According to Bob Adler, the steering column was DuPont 8540 or PPG 27627, which is a brown color. Most people it seems goes with the cab interior color for the column. But I did my steering wheel and column with Bob's advice. And I only have one reason why I think it is correct. It is the same color as the reproduction horn buttons, which are made either by GM or under license, so should be correct. I figure the steering wheel color would match the horn button.
