Ok so i'm gutting the '54 customline and obviously the wiring is trash so naturally i'm running all new wire everywhere. this is the first 6v system i have ever rewired and i am looking for pros and cons of 12v vs 6v. and if i switch to 12v other than the starter and generator (which will need to be swapped for an alternator i assume) what else do i have to completly swap or hook 12v to 6v reducers to. You should know i plan to use more modern 7 1/2'' reflectors with replaceable bulbs for headlights for safety and LED tail light bulbs, so those will be 12v compatible. Thanks for your patients i hate to ask what seems to be such a bonehead question but i really don't wanna foul up any of the original stuff because I was to proud to ask the question.
