Hey Mike. I know that Chevrolet made a lot of optioned cars. The heavy duty Muncie 3 speed on the column was an option, with the bench seat standard, with buckets and console an option. Some cars even were made with buckets , console, and column shift. Your car is one of those. Warren Lunig has a lot of information on these cars, and May have Yours registered. He just checked in on this sight. I would post Your questions on His post. NICK L72
