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. As a result, he engineered and built a robust Power Seat Transmission to replace the original. Since then, we've sold over a thousand seat transmissions for certain model years of Rolls-Royce and Bentley, and many models of General Motors from the late 1970s to the late 80s: Cadillac, Buick, Chevrolet, GMC, Oldsmobile, and Pontiac. We also offer the accompanying Power Seat Motor fully rebuilt.
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're looking for, feel free to submit a request.
Our product line includes 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, we have sold nearly a thousand ECUs globally. We can probably recommend a mechanic in your area who has experience with our product - feel free to contact us.
We have recently added two new parts for American Motors Corporation vehicles: Window Switch Mounting Brackets and a Window Cable Repair 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.
