Pin drive, thats a BIG one, as I'll bet NO ONE coming over has one of those!

Most wheels are held on with lug nuts, 5 or 6 more or less. On original Cobras they used that "spinner" you see in the middle of the wheel. The wheel has holes that much up with "pins", 5 or 6 usually, and these pins are what drive the wheel. The "spinner" is just there to hold the wheel tight against those pins (which act the same way lug nuts would, they drive the wheel).

I have lug nuts with a pretty trick wheel cover and spinner that makes it look like the "real deal". I prefer lug nuts over pin drive myself as it's much cheaper to buy a second set of wheels\tires for racing. Pin drive\spinners combo are BIG money!

So WHY did they run spinners (and still do on many race cars)? ONE "bolt" (the spinner) for a quicker change of tires during the race!

The bad news? ONE bolt, the spinner. That gets loose and your toast!
