Fiero RPO code list
Fiero RPO code list is a searchable reference list of RPO codes and option codes associated with the Pontiac Fiero.
RPO stands for Regular Production Option. General Motors used RPO codes to identify factory-installed equipment, options, colors, trims, drivetrain components, packages, and other build information.
For general information about RPO codes and the factory label that lists them, see:
Overview
This page is intended as a lookup list for codes found on the Fiero Service parts identification label.
Because an RPO label contains many different types of codes, a single master list is useful when the code itself does not reveal whether it refers to an engine, transmission, paint color, trim code, wheel, audio system, suspension package, or other factory item.
Use the browser search function to find a code quickly.
Cautions
RPO-code information should be verified carefully.
Some codes were used across many GM vehicles, and meanings can vary by year, division, model, or application. Some codes on a Service Parts Identification label may identify standard equipment, mandatory equipment, package content, paint information, trim information, or factory build details rather than a separately ordered buyer option.
Many Fieros have also been modified, repaired, repainted, engine-swapped, or transmission-swapped. The RPO label identifies how the car was originally built, not necessarily how it is configured today.

WA paint numbers
The WA number on the Service Parts Identification label is a Fisher Body paint reference number. It may appear as a WA-number code near the bottom of the label.
Paint suppliers may use the WA number to cross-reference the correct paint formula.
Two-digit paint codes, such as 14, 16, 40, 41, 53, 56, 71, 77, or 81, may also appear in paint references. A code such as 81U/16L indicates an upper and lower paint combination, with U referring to upper paint and L referring to lower paint.

| 8xx | Left rear spring |
| 9xx | Right rear spring |

Notes
This list is intended as a practical lookup aid, not a final authority for every GM or Fiero application.
When possible, verify codes against factory documentation, the original Service Parts Identification label, model-year literature, parts books, or other reliable references.
Some codes may appear more than once because their meaning changed by year, equipment, or application.
