I just recently swapped out the factory 'Base' model GT steering wheel with a brand new 2010 Shelby GT500 wheel that I got from Tousley Ford.
The factory wheel was the main part of the 'Base' GT interior that I didn't like.
I also changed the factory shift knob to a custom one that my wife got me for my birthday. It came from grabberpony.com. It is a black 'cue ball' knob and the 6 speed pattern is engraved in Grabber Blue! They have all the '05 and up Mustang colors available and you can get the ball itself or the engraving in those colors!
