These books won't be specific to your car but they explain a lot of how things are supposed to work. " Auto Mechanics Fundamentals" and "Auto Service and Repair" by Stockel. They were the standard autoshop cl*** textbook in the 60's and info most newer Techs never had to learn.
I agree with hemirambler, make sure the steering and braking systems are dead on right and reliable, then move on from there. Like you said, go through the hole wiring system. how are you doing it? At the shop what we do-which isn't necessarily traditional but its right, safe, and it looks old school-is we use painless universal kits and our electronics guy re-wires the visible wires with a cloth covered modern insulated stranded copper wire. The visible wire looks very traditional becuase it is a true cloth covering, but underheath is a modern insulated stranded copper wire. They work and look amazing, and that is how I'm doing my model A. You sound like you are all about the project, keep up the positive at***ude and that mental picture of what it'll be like when you're done and you'll learn so much as you go through. Keep us posted!
Like everyone has said keep it safe. Feeling your brake pedal hit the floorbroad when the light turns red is not the kind of rush I care to repeat.
Lessons learned the hard way. 1) When working on that stubborn nut or bolt, position yourself so you can pull the wrench toward you rather than pushing it away. You have more control if it slips or breaks and will have fewer ****** knuckles. 2) Wear the safety gl***es. Spending the night with a metal splinter in your eye, because the eye doctor won't be back till 10 am is no fun. 3) Just because that tire iron came with the car, doesn't mean it fits. 4) Listen to everyone, but do what you want and have fun with it.
