I cant wait for the fresh washed pictures of this car. Nice find. Dont forget to wash the shop vac out after you use it on the interior.
I know you said the wires under the hood were chewed badly. If you can dont just get the wire cutters out and go crazy. When you get the donner car home take good pictures before you pull the v8 out. Some things may stay the same. Same for the brakes (I would upgrade those asap) but you have to keep within your budget.
Not going to lie, I am a little jealous up here in Michigan. They are all rusty up here, if they were left outside.
