1966-1972 Oldsmobile
RPO Codes, Descriptions, and Applications

We crunched the numbers so you don't have to

Note: Most of the codes included here were derived from the Oldsmobile Chassis Service Manuals and/or other dealer references for the respective years. In some instances, we have attempted to clarify the descriptions and/or applications noted in the original documentation. In other instances, we have left them as is, which accounts for the inconsistent order of some items. We hope you find this list helpful in documenting the options your Oldsmobile left the factory with. Most of these codes will be applicable from 1965-1976, but not always.
The General Motors Regular Production Option (RPO) codes are a series of 3 alphanumeric
characters that identify specific equipment or features a vehicle had installed at the factory.
These codes appear in various locations, including the Body Tag mounted to the cowl
in the engine compartment, as well as on the broadcast sheet, or build sheet, if you can
find it, and they were listed on the original window sticker as well.
