Chevelle/Monte Carlo RPO by Year - A thru M  N thru Z

Notes:
* RPO codes are as of released by Chevrolet for U.S. Chevelles (except where noted).
* Not all Regular Production Options (RPO) were available for all years from 1964 through 1972.
* Some RPO codes were for internal accounting and not a 'check box' option such as B22, C56, YF8, etc.
* Some options may have been available on both Chevelles and Monte Carlos from 1970 through 1972, some may have been available on one or the other.
* Certain options were only available on certain models such as station wagon, sedan pickup, convertible, SS396, etc. and not available on all models in a given year.
* The Description may change wording from year to year.
* Some RPO items may not be listed for a certain year since Chevrolet considered them standard equipment within another RPO package. For example, the L34 engine is not listed for 1970 because it was the base engine with the Z25 SS Equipment option and, hence, not an option in and of itself. Dual exhaust (RPO N10) is another example; while it came standard with the RPO Z25 SS 454 option, it's not listed as a separate option for Chevelles in GM's report for 1971 or 1972.

Please check the individual years for additional clarification on any RPO items.
