Number 3 all the way. And do something with that grille. You might find that the 45 year old "tin" grille is subconsciously adding to your indecision.
The following grille style on number 3 would seal the deal since it complements both the modern wheels AND your intercooler. Just make an insert. Leave the grille's perimeter alone. Should be an easy experiment for Carter Hickman to perform.
Great work Carter.
