Body Plate Codes - 1964 through 1967

Codes listed are garnered from knowledgeable folks on ChevelleStuff Forums & the Chevelle Mailing List and will be updated as information becomes available. 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.

Codes are listed by Group and apply to all GM Fisher Body cars, not just Chevelles. Hence, you'll see option codes for "rally sport," "Z-28," etc. that do not apply to the Chevelle lineup or apply only in part such as the "Turbo 400." I'm currently removing items not known to be Chevelle options.

Note: n/a indicated the information is 'not available' or 'not applicable'; tbd indicates the information is reported but specifics are not known or is unconfirmed but is 'to be determined'. Some codes are reported from Chevy COWL TAGS, by Mark Allen and these codes are for everything in the Chevrolet lineup so they may or may not be applicable to the Chevelle series. These are noted by "(questionable concerning Chevelles)".
