Answer
Hi Jack,
That is the kind of stuff I do, but there is no way I can explain it on here.
You can easily replace the 6 volt batteries with 12 volt batteries, and still use the 24 volt starter.
You could also get a 12 volt starter.

But if you are not good at that rewiring stuff, a starter/alternator shop could probably be quite helpful.
