Chevelle RPO by Year - A thru M - N thru Z

* RPO codes are as of released by Chevrolet for U.S. Chevelles except where noted.
* The year columns with 'x' for each RPO are known to exist for that year and may or may not have been used in other years.
* 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 (verbiage) may change wording from year to year and even plant to plant.
* 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.

* Seen on 1970 Baltimore El Camino export and 1969 Malibu sport coupe export
** Shown on documentation but not a 'check box' option. Special Paint is known to have been available as early as 1966 as indicated by several early model year trim tags on this site. It may have been available as early as 1964. All Special Order paints had to be ordered through the Fleet & Special Order process. When talking about paint, generally this was used for fleet orders such as state vehicles or large company orders that wanted their cars painted a special color. This little known or advertised bonus was used by savvy buyers to get their Chevelles in another color. Generally any color that was available from any paint supplier that was available could be ordered.
*** Found in documentation and Canadian trim tag but not in options sold report
**** ZP5 & ZQ2 as a listed RPO in Chevrolet documents are shown only in 1971 & 1972. However, 1970 Kansas City build sheets show the same individual options and Kansas City shows ZP5 & ZQ2 as well where other plants do not. These (and a few others) are not reported by Chevrolet in their annual report as group options in 1970 however.

This 1970 KC build sheet clearly shows RPO ZQ2 as well as the two individual options included in the group.
***** It is not known what years this code is limited to.
****** Found on GM of Canada documentation.
******* Debate whether this was an option per sé or standard on all 1967 SS396 Chevelles.
