Mine have a notch on the bottom of the brackets, so it pushes against the radius arm bracket. They are metal tech, so yours are probably different. I think i had to cut out half the original front hole, but maybe not, ill have to look.
I want these arms, bad, but i have several things i need...
I could run em. I may(read:trying) go to the expo, i really need to.
My steering has moved to the front, with slee high steers and all that jazz. Only thing around there now is my sway bar.
