Hi & welcome from another Minnesotan.
Just a little tip on the positive battery cable. My '31 is on the road now for 4yrs and I had an 18" #1 positive cable on it and it turned over fairly well. Last week I installed a breaker switch [see pics]on the battery and had to turn it 1/2 turn for a better location for my switch under the floor board. This made me go to a 26" cable so I had one made up that was rated #OO. You wouldn't believe the extra spin I get off it now. Thanks to all the tips I got from this site.
So far I like this breaker switch set up.
Good luck on your restro.
