Ordered a Tilton 75 TIL-75-875U and there's no way it will fit.  the diameter of the C MC will rub on the 8.5 MC.  Running a T56 and Wilwood 6/4 on the Z.  Anyone else have this problem? Ideas? Seems like I would need a 8" or smaller MC or alternate Clutch MC than the recommended Tilton 75 series... ugh
