1957 1958 Cadillac Deville Eldorado Saginaw Power Steering Pump OEM 5685521 For Sale - New and Used

Up for sale is a rare, factory-original OEM Saginaw power steering pump with its complete round reservoir and cast lid, specifically casting number 5685521. This authentic vintage unit was factory equipment for 1957 and 1958 Cadillac models (including DeVille, Eldorado, and Fleetwood) built without the air spring suspension system. The assembly features the early cast iron lid embossed with "Power Steering Fluid Type A" and "Fill to Level with Automatic Transmission," along with its correct center retaining bolt and standard fluid return neck. This is an excellent, untouched core showing normal surface wear, grease, and patina from age—ideal for a high-end concours restoration or a period-correct hot rod project.
