I'm seeing more replicas of these around than anything these days. It's really cool because the basic design of both cars are the same, and it's a great setup.

Depending on what was the donor, and whether they're fiberglass or aluminum bodied, they're easy to spot. The biggest exterior give away is the knock-off wheels. There's a damn-good replica wheel available that looks just like the originals, but if you look behind the spinners, and there are lug nuts hiding there, nada. It's funny to see some of the guys even safety-wiring the non-functional spinners. The knock-off wheels and hub assemblies are CRAZY EXPENSIVE, so most builders don't bother with them.

But, hey... I see replicas at the car shows as well, and Carroll's autographed them without discrimination. You'd feel less guilty about rompin' on if it was not an original one... I've seen one at Lime Rock with a 9L engine, gutted, full tube aluminum chassis, 1350lbs and around 2000hp. It ran ONE lap of the big race, and pitted 24 seconds in the lead just to give about 24 other big-block Fords a chance. I think it would definitely be a car design worth building.
