I hate to say it, but Good Luck!. I've been searching myself for a long time. The C5 Y2K replicas on my car are not from OE wheels. Apparently made by Topline back in the day, which is now Verde Replica wheels. Anyways, my center caps were glued in by the previous owner because they keep falling out. After installing new tires, I've since lost one of my caps. CANNOT find any without the logo, just as mine are. I've also tried getting just 4 new caps from every other C5 Y2K replica manufacturer, including OE wheels, and no body will sell just the caps. Gotta buy their wheels!

The only thought I came up with was to use some sort of filler, like a bondo or something, to fill in the Corvette emblem of the factory caps. Then just have them repainted. Never really looked into it. I just bought a new set of wheel instead.
