For the tall retro-looking numbers, I'm going to guess that you will have to wait awhile before someone comes out with them. Right now everyone is concentrating on putting out 05 6, and mostly GT upgrades. You'll have to wait for the companies to iron out any problems with their products first after people start ordering, then complaining about the parts, and then the companies fixing what's wrong.
I've looked at more gauges than I care to, and haven't found anyhing remotely like that which would fit and function properly in a six.
Speed Hut didn't have the correct fonts for the gauges.
