Has anybody ever drilled out the uni-ball on the frame side to fit a 1/2" bolt to get rid of the 10mm one. Just wondering how hard the material is and if it would leave enough left on the uni-ball to not weaken it. It is a difference of .107 inches.

RE "extreme-duty" trac bars have 1/2 inch holes now. You can purchase the ball direct. p/n RM13562
