- GM third-generation F-body SPID labels and door plates, 1982–1992 — Camaro Z28, IROC-Z, Firebird, Trans Am, GTA, the 20th-anniversary Turbo. RPO-coded; California vs. 49-state and export variants tagged.

how Plenum is different›
- Honest uncertainty — every code carries a confidence tag and a citation. Disputes show both readings.
- Plant-aware — Lynch Road is not St. Louis. The schemas know.
- Damage-friendly — burned, torn, marker-defaced sheets get partial decodes. Never fabricated.
- Runs entirely in your browser. The decode engine and the OCR are both client-side. No accounts, no analytics, no server in the critical path.
