Welcome to Proper Parts

We design, manufacture, and refurbish high quality aftermarket auto parts for several model years of Rolls-Royce, Bentley, Range Rover, and General Motors vehicles. We sell Power Seat & Mirror ECU Control Modules, Power Seat Transmissions and Power Seat Motors, in addition to many parts associated with these systems. If you can't find the obsolete part that you're looking for, feel free to submit a request. We’ve been building “Better Than New” since 2006.
