not fixed but little update:
there are three different bolts holding the box to the bracket. <img src="/forums/images/graemlins/zombie.gif" alt="" /> i think one is not threaded all the way b/c it's tight but i can wiggle the washer. i'm also worried someone forced the wrong thread bolt in there b/c it doesn't want to come out either. the box is moving on the bracket AND the bracket is flexing. this has to be most of the problem. the bracket looks fine but i guess i will get a new one and maybe one of those stabilizers. how have these worked for ya'll?
