Here are some pics of mine. 3X5 turned on an angle, then cut the top corner off to make it flat. Plated it with some diamond plate so i've got something to stand on to get to the roof or in deep water, etc. Used inner and outer hitch reciever material to mount them. Large side on the frame, then slid the nerfs with the small side into them. I was going to use bolts, but got lazy, so I put a couple of short beads on each mount. Now if I need to take them off, I just have to grind a few short welds and they'll slide rite out.
