Even though the donor itself is 30+ years old? Think I'd have trouble with the bulkhead box? Looks all gooey under hood. A sealer maybe? Perhaps I could strip down the donor box to what need... I was thinking my wiring needs were simple...lack of electronics.

Do you guys think it would be worth while to buy a cheap kit and build off it as I go?
Or use donor. Labor wide it wouldn't be fast but...i have a lot of time between my steps.
