Front sway bar

I have a C4x4 Pro rock front bumper on my '90 XJ. I also have RE front sway bar discos. My problem,is that the sway bar is rubbing against the bolt head that mounts the bumper to the frame rail. When the suspension flexes,it squeeks like crazy! I tried spaying penetrating oil on the area but it only works temporarily. Any suggestions? Thanks.

Ok... on a more serious note... is it because the head on that bolt is HUGE or because there is just no space? If the former the look for a smaller bolt of the rights size....

The bolt head is 3/4in. There isn't much,if any, space between the bolt head and swaybar. Could I grind the head down some to create more space? Also,It only squeeks on the passenger side.

Is the swaybar centered?
