shifter knobs?
 

My dad has bought a 2005 C6manual Corvette and has recently installed the Hurst short throw shifter in the car. He's wanting to change the shifterknob but we are finding a serious lack of options available for the C6 everywhere we look. He's looking for a black ball knob with the C6 crossed flags in it. A thread-on type will work fine because of the new shifter, just we can't find ANY knobs with a C6 logo. Thanks for any help on the subject.
