Oldsmobile paint codes were placed in many different spots over the years, making them difficult to locate. The plate is often in the glove box or the spare tire well; if not there, locations vary widely. Codes typically appear like 51/WA316N and are usually preceded by BC/CC (e.g., BC/CC 51 or BC/CC 316N). Two-tone plates may use U or L for position, such as BC/CC U316N or BC/CC L316N.
