Well i have a jeep grand cherokee 2004 and im ordering a brush guard, or grille guard or wat ever you want to call it, everyone that is selling just shows the big hunk of steel in the picture and no little pieces to get it hooked to the front of my car. I dont understand, do i need anything to actually intstall it or does it like hook right in? Someone please explain in detail wat all i have to do...
