Congrads. on your find. Hope it is everything you wanted.
Sounds like you have allready a good list. Some one mentioned before the you should do some basic check before you go any further.
1. Brakes; if it wont run well thats ok if it don't stop don't drive it.
2. Steering; This is a tossup with brakes with brake failure you can (maybe) steer around it. Without steering you are up a creek with out a paddle.
3.Running gear; Is it full of water/oil mix? Who knows untill you change the lube.
4. Engine drive ability. the last stage of inspection and repair.
After all this you need to figure out what you are going to do with this old bolt. Daily driver?
Show truck? Or trailer queen?

I didn't do it, no one saw me do it, you can't prove anything! "Bart Simpson"
