Rich,
If you were willing to consider a '62 aluminum car, the Zintmaster car is for sale through Fraser Dante in Ga. This car is one of 18-20 (no one really knows for sure) Factory built B/FX '62 Super Sports. The car currently has a Z-11 top half on it (which is incorrect as they were all std 409hp). Although a lot more rare than a '63 Z-11, they weren't as complete of a race car package as a Z-11. The Zintmaster car is incredibly original (other than the top half) as it wasn't raced very much at all. It's priced at $275K. which is what you'd pay for a non-original (but authentic) Z-11. It may very well be the rarest and most valuable '62 on the planet, other than the Strickler '62 Belair.
Just thought I'd mention it for your consideration.
