Solid-State Voltage Regulator Conversions

Its a 1944 Willys Mb military jeep. Its the L134 4 banger, Im not using an alternator, Im using an original style generator. My problem here is that the original voltage regulator is 6v and I need to convert it to 12v. There is a company doing it but for $100. I think I could save some if I do it my self.
