1944 Farmall M Project

[WC Haire]

I'm rebuilding an M just for show. I want to try to stay as original as possible but a lot of people are converting the 6 volt system to 12 volts? Just wondering what the pros and cons of changing or not changing is.
Thanks for the help.

Is it a little late to reply? I think the main reason to switch was starting. 12 Volts will really spin it over and almost all the M's were hard to spin over with 6 volts unless everything was perfect.
