I have 4 of mounts along both sides on mine. The front one is made from 75mm Box and bolts on at a mounting point on the chassis. The other 3 are 50mm Box with u brackets made with 8mm flat and have 2 bolts through the top. When it dry's up up here I will try to take a couple of pics for you. May be a little difficult as I have 8mm flat running along the distance of the mounts.
