I took a couple pics for ya , the sway bar is bout 13" infont of the cradle depending on where you measure it , its 3" down from the bottom of the frame , 4 1/2" from the center of the idler arm nut and 12 1/2" from the bottom of the bumper , sounds like its gonna be close to where you need to be , could possibly go overtop of it , maybe trim the bottom off the angled crossmember and reinforce it
