I have read a number of posts about the
hassles of the breakoff screw on the AFC, and how hard it is to remove.
It is easy. In the center of the head is a small dimple, that will be
your starting guide. Use a 1/8"x6" drill bit, carefully drill a hole
3/16" deep. You will want to follow the angle of the bolt, that is the
careful part, keep the drill in line. Take a #20 torx bit and hammer it
into the hole. The splines will easily cut themselves in. Once bottomed
out, add a socket to the torx bit and remove the bolt. It takes 5
minutes, no hammering, no pounding, no beating. If you do completely
screw up, the only thing that will happen is that the top of the bolt
will shear off. Remove the other AFC bolts and using vice grips take
out the sheared bolt. I have never had to do that though, the drill
method has always worked for me. Good Luck.
