How to read the master table

One row per code; the Years column is the overall span seen across the listed model docs (availability differs per model — always follow the model doc for exact years).
A code could mean different things on different models or in different eras (GM reused codes); such rows are flagged and the model docs carry the specific readings.
Confidence: confirmed = 2+ independent sources agree for at least one model; single-source = documented in one source only; disputed = sources disagree (details in the model doc).
Numeric codes at the end of the table are 1960–62 full-size ordering codes (pre-RPO system) and interior-trim/paint accounting codes.

Known gaps (division level):

Full-size 1963–82 per-year option availability is only partially mapped (division-wide list without exact years for many codes).
Chevelle/Malibu 1973–77 Colonnade options not yet tabulated per year.
Camaro 1970–81 codes lack per-year availability for many entries (dealer-order-guide list is generation-wide).
Monte Carlo 1973–82 and Vega/Monza carry package/powertrain level coverage; several late-70s RPO letterings (Iron Duke I4, T-50 5-speed, 231 turbo V6) remain unverified.
Paint, vinyl-roof and interior-trim accounting codes (two-digit + letter, and 3-digit trim codes) are intentionally not exhaustively listed.
