Cool... I'll call them. Mario this is a good thread in the auto-x/RR section of CF about aftermarket steering wheels and horn switches etc. etc. etc.
Aftermarket steering wheels - Corvette Forum
You can make them work for sure... just wasnt' an issue for me. Some of the wheels have a provision for a button in the center and others will require a horn button that goes on a plate between the wheel/hub and sets the button to the side a bit.
