The area where the fuel lines go through the unibody is COMPELTELY gon, lol. I think what I will do is insulate them similar to what you said, weld in the metal i need to weld in, and then seal the fuel lines to the unibody with POR15. All of the interior of the car will be POR15 coated, and I plan to undercoat the whole thing with POR15's rubber undercoat. If it rusts then, I'm going to beat up POR15's CEO!
A few pics from today after work.
Windshield wipers don't work, so that is what I am looking into next. (they worked according to an inspection paper I found in 2012, so....)
