Clutch Pivot Ball
 

I'm thinking about going from the stock 11" clutch to a KC. However, from what I hear, the KC has a thicker disc (Ford used .27" discs for the 11" disc and regular .31" for 10.5" discs) so would this cause any geometry issues? If so, I'm assuming I need an adjustable pivot ball. If I need this, how do I know I adjusted it right?
