[Unreal]

I'll have to check my originals and my recent GM ones against the pics, but I think my new GM ones have a more distinct ribbing pattern.
I remember the NOS with rivets ones. I always thought the older NOS had rivets, and the newer GM did not. If that's true, I wonder where the NOS w/rivets set came from?

maybe extremely early NOS (like maybe while the first gen was still in production) had rivets. I wonder what the date is on the ones in this auction w/o rivets.
