These black bolts are absolute garbage. I haven't messed with mine after my little "mishap" The bolt literally destroyed the lower mount on the way OUT... It is almost as if it were crossthreaded to begin with. The bolts are NOT polished and the rough surface causes significant gauling which destroys the soft aluminum of the lower. 06 owners beware, and be carefull that the bolt is ABSOLUTLEY coming out slowly and with little force. If it feels sticky at all, the lower is trashed...
Here's mine...
