Hey guys, I have a 54 3600 that needs a new starter. The truck has been converted to 12V since when I bought it it has always had a 12v battery. It has cranked slowly for years but finally gave up the other day and I took the starter off and apart and the insides are shot. The brushes are literately worn down to the arms that hold them.... Can I use a 6v starter or does it have to be for a 12V system? I don't see where they are different in my research. A lot of the other components are but seems the starter can use either 6V or 12V? Any help/advise is appreciated.
