I've got a 95mm Wilson throttle body for sale. I bought it without asking enough questions and found out the hard way that it WILL NOT bolt up to a stock LS3 intake. This throttle body is designed for aftermarket applications where a sheet-metal intake or an intake-elbow on a 4bbl intake is used. This is the Wilson 471095 unit. It uses a Ford IAC and ford TPS, but there are adapter kits available that will allow you to use the GM IAC, and Wilson sells the TPS with the GM-style plug.
Though I bought this "used" it appears to be in 100% new, unused condition. I can't see any marks that would indicate that it was ever mounted to a car.
These sell for $390 new at Summit Racing, I'm asking $300.
I can't post pics right now because I was a little lazy in renewing my website's domain name, so DNS servers don't seem to have updated yet. I expect to be able to post pics in the next day or two, but in the mean time, if you're interested, please email me at jim85iroc at gmail dot com and I'll send you some pics.
Here's a pic from summit's website:
