Restoring a Buick requires more than just "GM" parts—it requires components engineered specifically for the unique luxury and performance standards of Flint, Michigan. Unlike Chevrolet or Pontiac, Buick often used unique engineering designs (like the torque-tube drive and specific electrical connectors) that universal replacements simply don't fit.
At Old Car Parts NW, we specialize in authentic NOS (New Old Stock) items for the discerning Buick restorer. These are the original "Factory Engineered" parts found in the dealer parts bins of the 1940s through the 1980s.
Serious Buick collectors know that accuracy matters. We catalog many of our parts by their original Group Number (e.g., Group 0.000 for Engine, Group 2.000 for Electrical) to ensure you get the exact part for your build sheet.
Engine & Drivetrain: Hard-to-find mechanical parts for Straight-8 "Fireball", Nailhead (401/425), and Big Block 455 engines.
Interior & Body: Rare NOS switches, emblems, and lenses that feature the correct chrome finish and script—details that cheap reproductions always get wrong.
Suspension: Factory-correct knee-action shocks and heavy-duty suspension parts designed for that famous "Buick Ride."
The Chrome Era: Roadmaster, Super, and Special (1940s-50s).
Muscle & Performance: GS, GSX, Grand National, and Riviera (1960s-80s).
Luxury Cruisers: Electra 225 ("Deuce and a Quarter"), LeSabre, and Wildcat.
