making stuff...and a little bit of progress
Regarding the generator field wire, I contacted Vintage Wiring of Maine, and they made a short jumper harness that will connect the new main harness to the existing wire on the generator. They were really nice to work with.
Other stuff:
After putting my steering column together, I realized that I was probably missing some type of plate at the firewall (see the red dotted line in the pic below)

I don't know where it went but it is either in a mystery box of parts or it is long gone. Jeepdan confirmed that I was indeed missing something (Thanks Jeepdan!) and the manuals don't show it, so I had to fab something up. Based on the witness marks on the original foam gasket, and the shapes of the existing parts, I came up with something like this:

I also found some foam rubber on the internet and re-made the seal at the base of the steering column:

The same stupid kid (me) that lost that plate at the steering column also tossed the clip that holds the throttle cable at the firewall. So I had to make a new one of those too. I used the clip at the carburetor as a pattern. (I made it out of a stainless steel ruler that was conveniently at hand;)
