Looks are one thing, but if you want your musclecar to actually perform I'd stay away from the reproduction tires. The tread designs are outdated, and the compounds available are straight out of the '70s.
I'd go with a modern design, modern compound tire if you're actually planning on doing something other than driving your car to the show and back to the garage. The Nitto is a decent tire, and will give much better results as far as handling goes than any reproduction, or even the BFG T/A's. The biggest problem is finding decent tires for a 15" rim, a lot of the better performance tires are only offered for larger rims now...
