All, I just got done installing my EVO3 UCC SSK on my e39 540. The nob is slightly off center. I just need to rotate it abit. There is a set screw in the center of the shifter shaft. What does that do? It has a wierd hex head with a pin in the center - none of my alen wrenches will fit because of that pin sticking out.

Thanks,,
