Unidentified Option Codes


Recommended Posts

Can anyone identify the following option codes? My '94 service Manual doesn't have them listed in the option codes section.

And does anyone know what the code R1P, "Chassis Equipment, Heavy Duty, Coachbuilder" buys you? I would like to specifically identify what parts or modifications make up this option. I never knew the vehicle had this specific option until I finally investigated the installed options label.

Vehicle is a '94 Fleetwood

If no one can give you an answer here, a dealership might be able to tell you.

If you really want to make people safe drivers again then simply remove all the safety features from cars. No more seat belts, ABS brakes, traction control, air bags or stability control. No more anything. You'll see how quickly people will slow down and once again learn to drive like "normal" humans.

Found the info on the Yahoo Cadillac owners website....


Regular Production Option (RPO) codes are a three-digit combinations of letters and numbers. They identify standard equipment and in most cases some optional equipment that is installed on the vehicle at the assembly plant. Also contained on the SPID label are the trim & paint colors.

Certain GM accessories can be ordered at the same time the vehicle is ordered. These are called Regular Production Accessories (RPA). The accessory is listed on the vehicle’s window label and SPID label. However, the RPA does not accompany the vehicle when it leaves the assembly plant. Instead, the item is shipped directly to the dealership for installation at the time of delivery.

Below are the most common RPO numbers you are likely to find on a Fleetwood. A RPO Master List that includes every RPO code used within the last 20 years is available in the Regular Production Option Master List (PDF, 1.1MB), the RPO codes are arranged in alpha-numeric order, and this list is huge, containing more than 18,000 items.
