mine are 3/8 bolts, put them in myself, non the less, I dont want to mount it to the bumper. I'm thinking of a tri-pod (quad-pod) style setup,, from the front suspension to the middle just above the bumper, then from just in back of the bumper build a little something that would clear the bumper and then mount a plate on. where b is the bumper, I is behind the bumper and in front of the rad and 0 is the round bar holding the front control arm assy. / or \ is in front of the bumper. thereis enough room on the passenger side to reinforce it towards the frame about another foot back towards the frame
