New Lucas Replacement E.T. Ignition Coil. Finding an original Lucas E.T. (energy transfer) coil is almost impossible to find. Either they are too expensive or damaged beyond use and repair. These new E.T. coils by EMGO will replace Lucas part number 45149 and 45150. We have used these coils on Triumph and BSA models in our shop that feature the energy transfer ignition system with no problems. Please keep in mind that you will have to make a bracket or modify your bracket as the specs are slightly different from original E.T. coils. Works with singles or twins from the Triumph T20C, B44, A65H, TR6C, TR6SC, and more. Please refer to your parts book to ensure the best fitment.***Measurements***–Mounting hole spacing 1 5/16″–Thickness of bracket 7/16″–Length of bracket 2 1/4″–Spark plug wire 18 1/2″Made by EMGOO.E.M. part number is 45149 and 45150
