Welcome aboard. Get all of your electrical connections and grounds done first. Start at the headlight sockets, work your way to the tail lights. You will need some small s/s wire brushes, contact cleaner. Toothbrush and gun cleaning type sizes. Dielectric grease. Replace all of the fuses, bulbs with quality parts. No China/Taiwan stuff. This will save you a lot of time chasing down electrical problems as they were common even back then. Don't cheat, you will only hurt yourself if you do.
