Ulli, Rob from PJ Grady has a Delco digital 105 amp output alternator for sale to replace the two different original alternator that came in the DeLorean. This Delco unit "sits" in the same location with no alteration to the original mounting brackets. All it need is a simple change to a wire to accept the new terminal for the Delco alternator. It is a 15 minute installation job once you lift up the car to get access to the alternator. Kayo Ong #05508 Lic. 9D NY
