If you are tired of the slow, intermittent, and/or non-functioning window lift motors in your Aston Martin DB5 or DB6 then this conversion kit will solve all your problems. This uses a modern window motor with an adapter that allows it to bolt right onto your existing window regulator with no modifications. As the original Piper window motor, which is no longer available, had internal relays our system comes with an external relay pack that mounts inside the door. The wires are color coded as original so they just plug right into your existing harness. These motors are handed left and right so please specify what you need when you order. This listing is for one motor only.
