This doesn’t exactly answer you question but, you don’t need to take that stud out, do you? I’m pretty sure the ksb1 goes on that stud, even if they ship another with it. Or is the new stud larger in diameter? Pretty sure the chill r uses the same stud as the heli m uses, which the ksb fit on with no problem, as I remember.
