I'm going with Hot Wheels 65. Kinda hard to find (try Discount Tire) but they look like a modern take on the old Magnum 500 wheels without the black between the spokes and just like the wheels on the Hot Wheels I grew up with.
As for the hood, if your set on painting it, try just the inside stripes and the vents. That would give it accents similar to the the Challenger rally hood.
