I think before I vote, I need to know one thing... Are you resto-modding this car with 4 wheel disc brakes? The wheels honestly look so similar there isn't much difference. So, I'm asking because you will want to show off your rear disc brakes if you have them. I had 4WDisc on my '65 Mustang with Magnums and honestly you cannot see the brakes at all. They only have a little rectangle to peak thru the wheel to see rotors. If you have the 4Wdiscs then I'd go with the modern more open wheel.
My 2 cents.
