special wheel nut socket

[mackguy]

Hey everyone,
Going tomorrow to pick up my "new" 40th Anniversary ZR-1. I did look at it in person before, but learned some new things about them reading through the owner's manual PDF, and I'm a bit puzzled at one thing.

The owner's manual indicates that there should be a special socket for the locking lug nuts, which is straightforward, but it also mentions a "special wheel nut socket" and says you should never remove the lugnuts without it. But searching Google, Youtube, CorvetteForum, and here I haven't found anything about what it is, what it looks like, etc so I can verify it's in the car.

I also can't find anything listed in the catalog companies I checked (Ecklers, Corvette Central, Zip, Mid America).

So... what is it, what's it for, and what does it look like?
