You are worried about 0.011" diametral clearance difference? If this is the master cylinder you want to use and the holes are too large to suit you, I'd just sleeve the holes and ride off into the sunset.

The problem is the heads are round, no hex, like a wheel stud, and they fit loose. Try tightening up a wheel with a spinning wheel stud.
