Chevy II / Nova — RPO Codes (1962–1979)

Compiled primarily from NovaResource's RPO production-number tables, which were assembled from GM records (Acadian production is included in the 1968+ totals; 1962 and 1970 source records are incomplete). A year is listed for a code when GM recorded production of that option for that model year. Confidence is confirmed when the code also appears with the same meaning in at least one independent source (Chevelle, Camaro, full-size or division-wide lists), otherwise single-source.

Note: 1968–79 GM records also carry dozens of paint (xxL/xxU), vinyl-roof (xxT), interior-trim (xxN/xxR/xxV/xxB/xxC/xxD/xxE etc.) and numeric trim codes. Those color/trim accounting codes are excluded from the table below except for a handful of historically significant entries; see the source for the full color/trim listing.

Package notes, 1968–79:

Z26 — Super Sport (1968–1976): the Nova SS became an option package in 1968 (previously tied to the Z03/SS model). Big-block L34/L78 396s were available 1968–70 with Z26.
Z26 — Rally Nova package (1977–1979): code reused for the Rally Nova appearance package after the SS was dropped.
Z11 — "LN package" (1975): Nova LN luxury model equipment code — unrelated to the 1963 Impala Z11 427 or the 1969 Camaro Z11 pace car.
Z51 — Spirit of America (1974): red/white/blue appearance package (also offered on Impala and Vega).
COPO 9010 / dealer conversions (1968–69 427 Novas, e.g. Yenko): documented as Central Office Production Orders, not RPOs; excluded here.
