Thanks for the responses and opinions. I am partial to the 6v system. I converted the 2A to 12v because it was very simple. This truck is not overwhelmingly complex itself, but I am leaning toward original. As for the other side, there has been some new paint sprayed on at one point in time and it does not have near the appeal as the drivers side, but it adds to the story and character of the truck. There is an in-line 6 cylinder in this truck which I am beginning to understand is not the original motor. The word 'Hurricane' is cast into the top of the head on the intake side so I am assuming it is a F-head. I will get a picture up soon. I have attached a few more pictures of the exterior. More to come soon...I hope.IMG_1073.jpgIMG_1072.jpg
Yep. Starter current draw was one of the reasons that forced 12-volt systems. As engines moved to higher compression, cranking currents became unreal. On the little Jeeps and the trucks with 134 CID engines, stall current on the starter is almost 500-amps. When it goes "ARUMMP" and hangs for a second on a cold morning, the 6-volt battery is delivering a huge slug of current to the starter.
That's why you don'y try to get away with parts store #2 AWG battery cables.
