hi guys, the engine in my herald convertible is a spitfire 1300 USA high compression model. engine number fd16815he with twin carbs. i am trying to find the correct distributor for it and have been told it should be either the lucas 25d- lucas 45d- or delco remy 202/204 or even the DR 200????? help confused.. i have a 25d in at the moment and it runs (not on road at present) i also have a tatty 45d will look for a delco if necessary. but what difference will it make if i have the wrong one?kinda of stuck as would like this for my daily driver so really has to work as best as is possible. hope someone can give me a clue. cheers rob
