All your light bulbs, Generator or Alt in 12 volt, I will assume your running a 1500 to 1600 engine, So if your tranny is a 6 volt and has never had a 12 volt flywheel you will need to remove some extra material from you tranny, and change the bushing for the starter.
You either need a 67 wiper motor or a volt a drop, Or you can just have a really really fast wiper motor that you might need to change every now and then. 12 volt flasher, and 12 volt starter, Or like the wiper motor, have a really fast starter for a while!!
My uncle lester just fires up a dual port and shoves it into a 6 volt tranny, Its kinda funny to watch, but works like a hot damb!!
(do not try this method, Lester is a little F&$&## up)
.
And dont hook your original radio up!! Unless it has a 12 volt selection dial on it, some of them do.
