The cowl-mounted data tag contains valuable information about the vehicle it’s installed on, and this Firebird is is no different. The most pertinent data is found on the second and third lines. The “19R” and “19L 19U” found on line two reveals that it’s equipped with standard interior in black vinyl and a Starlight Black lower and upper exterior finish, respectively. The “04C” found on line three indicates a build date that occurred during the third week of April. The “WS4” on that same line positively identifies it as a Trans Am model. The fender bolt appears to be finished in black phosphate plating. The red-oxide primer basecoat is present wherever the Starlight Black exterior color and semi-flat black dash color wasn’t oversprayed.
