Thanks for the replies. I have a 1947-54 Chevrolet Truck Factory Assembly Manual on the way as well as some other misc parts I need for this truck.
Concerning the wiring, the previous own(s) replaced the factory under-hood wiring with modern wiring which isn't taped up or wrapped with anything (it's a mess). I would would like to restore it to stock-appearing which is why I asked for pictures (thanks, papas52).
Here's some pictures of what I'm working with:
