for the rear upper bracket (oem) it would have to be removed and weld a flat bracket with gussets on the sides. oooooorr you can notch a good section of the upper bracket to have clearnce for youre fitting and air line. i would recomend that you don use 1/2 line,it will be hard to bend it up there.what i did on mine was welded the bottom bolt to the bag, then spund the bag around to screw it in, if you need to to remove it or work on it just raise the the body let the axle go as low as it can and the upper part of the bag will be loose enough to screw it off.
