Modern electronic ignition is available for cars with 25D4 and 45D4 distributors. Modern Japanese electronics have been combined with the looks of the Lucas 45D4 distributor to give you the best of both worlds, maintenance-free ignition with the original look of your British distributor. The 45D distributor will replace the distributor in any A-Series engine. Use this distributor with a 3 OHM coil, such as: DLB101, DLB105, 40501, 40511
See 3H2138 for hold-down clamp.
