Hi Jim,
The series of codes you've found on your Buick's body plate, "ST 71-4467 FL1 161751 BDY" and "TR 156 53 B PNT", offer a detailed snapshot of its production. Here is a breakdown of what these alphanumeric sequences signify:
- ST 71-4467: This indicates the style and model year of your car. "71" is for the 1971 model year, and "4467" is the style number for a Buick GS 2-door hardtop coupe.
- FL1: This is the assembly plant code, designating that the vehicle was built in Flint, Michigan.
- 161751 BDY: This is the Fisher Body number, a unique identifier for the body shell of your car.
- TR 156: This is the trim code, which specifies the original interior trim of your vehicle. In this case, it denotes a black vinyl bench seat interior.
- 53 B PNT: This is the paint code. The "53" corresponds to the lower body color, which, according to 1971 Buick paint charts, is Cortez Gold Poly. The "B" indicates a black vinyl top.
Therefore, your 1971 Buick GS was originally painted a metallic gold color with a black vinyl roof.
Despite your car's original color, your interest in a gray or silver metallic appearance is well-founded, as Buick offered several such options for the 1971 model year. If the car has been repainted, it's possible a previous owner chose one of these stylish alternatives. The factory-offered gray and silver metallic colors for the 1971 Buick GS and GSX included:
- Platinum Mist Metallic (Code 13): A classic silver hue with a metallic flake that would have given the car a sleek and sophisticated look.
- Tealmist Gray Metallic (Code 16): A darker gray with a hint of teal, providing a more unique and subtle color choice.
It was not uncommon for these classic muscle cars to be repainted over the decades to suit the owner's preference or to refresh a faded original coat. Should you decide to repaint your vehicle, these factory-correct silver and gray options would be an authentic choice for a 1971 model.
