The vehicle option codes are on a sticker in the glovebox of your Chevy truck. You are looking for a 3 character code starting with M. Match that code to the table found here and you should find your answer.

Hello. You can open the driver's side door and find the white card on the side of the door that is filled with small black lettering. This card contains specific details about the year the car was made, its transmission, engine specifications and other details Spam removed
