Body Plate Codes - 1964 through 1967
Select a year
[ 1964 ] | [ 1965 ] | [ 1966 ] | [ 1967 ]
Codes are listed by group and in alphabetical order within the group. Codes listed are for all 1964 Chevelle body styles so some would naturally not apply to the El Camino. Codes on trim tags are not shown in alphabetical order but they do have an order of precedence when used.
| Group 1 - No number precedes Group 1 | |
| D ~ Power convertible top [RPO C06] | E ~ Tinted glass (all) [RPO A01] |
| F ~ Power bench seat [RPO A41] | G ~ Power tailgate [RPO A33] |
| O ~ Suspect sat belt delete [RPO A62] | T ~ Power bucket seat [RPO A46] |
| W ~ Tinted windshield (only) [RPO A02] | X ~ Power windows [RPO A31] |
| Group 2 - preceded by the number "2" | |
| K ~ Air conditioning [RPO C60] | L ~ 4-speed transmission [RPO M20] |
| M ~ Powerglide transmission [RPO M35] | N ~ AM/FM Stereo multiplex [RPO U79] |
| P ~ Comfort & Convenience group [RPO Z01/Z13] * | R ~ Rear speaker [RPO U80] |
| S ~ Rear antenna [RPO U73] | |
| Group 3 | |
| B ~ Rear window defogger [RPO C50] | C ~ Instrument panel pad [RPO B70] |

| Group 5 | |
| O ~ Unknown - Suspect seat belt delete [RPO A62} **** | W ~ Custom deluxe seat belts with retractors [RPO A49] |
* RPO Z01 is Type A (Malibu/Malibu SS) and Z13 is Type B (300) with difference being the remote mirror is included with Type A. (It's not uncommon to see both Type A and Type B shown on trim tags with Type A.)
*** The letter "L" isn't known on Atlanta & Framingham Chevelles. It is believed this letter "L" is not in group 5 as it has been found on several tags with no group 5 designation.
**** Found on Euclid 02D Custom El Camino built for the KC assembly plant
If you have any codes to donate to this cause (or find any here that are incorrect), please contact me specifying the model year, group number and letter designation. It's reported that some plants used different option code letters for the same option. Also, only Atlanta, Flint, Framingham, Kansas City, and Van Nuys used these codes on the body plate; Baltimore and Fremont did not.
