Proper Parts was founded in 2006 by Alex Porti when he couldn’t find a replacement Power Seat Transmission for a 1981 Rolls-Royce Silver Spirit. This led him to engineer and rebuild a robust Power Seat Transmission to replace the original. Since then, we have sold over a thousand seat transmissions for certain model years of Rolls-Royce and Bentley, as well as many General Motors models from the late 1970s to the late 1980s: Cadillac, Buick, Chevrolet, GMC, Oldsmobile, and Pontiac. We also offer fully rebuilt Power Seat Motors to accompany these transmissions.
We provide a variety of essential components for these Power Seat Systems, including switches, seat rail bushings/track glides, couplers, gear drives, square drive cables and sheaths, actuators, retaining clips, jack screws, screw drives, retaining plates, and escutcheons. If you don't see what you need, feel free to submit a request.
Our product line also features newly designed Electronic Control Units (ECUs) that control power seats and mirrors in Range Rover Classic, Rolls-Royce, and Bentley models. Since their launch in 2011, nearly a thousand ECUs have been sold worldwide. We may be able to recommend a mechanic near you who has experience with our product, feel free to ask.
Recently, we added two parts for American Motors Corporation vehicles: Window Switch Mounting Brackets and a Window Cable Rebuild Service. We are pleased to broaden our support for the classic car community.
We manufacture quality products that cannot be found anywhere else with exceptional warranties and a fair price. All our parts are designed and manufactured in the United States. Proper Parts is a privately owned unaffiliated company. We sell directly to restorers, dealers, and individual car owners in the USA and internationally.
With over 25 years of experience restoring Rolls-Royce and other classic cars, we have the troubleshooter's perspective and are always developing new parts. We aim to build Better Than New.
