I have been testing a Hurst shifter prototype in my 2005 MUSTANG GT for a while now and it works great. The guys at Hurst are looking for another 05 GT to test the billit version of the Hurst shifter. They would need the car for a few days (In Cleveland, OH) and would compensate you by giving you a production shifter when it is ready or by giving you another equal value product immediatly. If anyone is interested you can call the engineer for Hurst. His name is Keith Braun and his number is 216-658-6293.
I definitely would. I own a 2005 5-speed GT. I also have a 2002 F-150 and got a prototype shifter for it as well. Is that Jim's number (Mr. Gasket) you posted?
