Curt,
I will confirm they are not greater than 9/16". By the tape they are between 1/2" and 9/16" - need a mic on them. The set I did originally, I tappered after the ball studs were removed. As easy as it is to remove them, I say just do it.
The key on mine is that the chamfer is on the top (ball side)and press them down and out toward the bottom.
