If you are refering to the rear upper mounting bolts, that attatch the alum. arm from the suspension to the tunnel. You need to modify a 7/8 (I believe) open end wrench to fit around the 2 sided inner retainer. It needs to be ground down to about 3/16 wide to fit in there. If you look with a light, and turn the bolt from the outside, you will see the flat areas that you need to get the wrench on.. Kind of a lousy design, if you ask me, but it works. Pain in the butt though. The bolt will be locktighted, so it will spin out with some resistance all the way. Locktight it back in too.
