factory front mounts suck. they are only good for hold up an bumper and waiting for a crash. no good at all for yanking on to get you out of the mud. rear mounts are a bit better, but I did the same thing for mine, front and rear. I know there are aftermarket rear brackets out there. don't remember who made them though.
these are the ones I built, but I imagine you can get aftermarket ones by now. (bent by the same shop from which I bought the steel) this shot was taken during mockup so the pin hole for the hitch hasn't been drilled yet.
built my own clevis thingie. :D
and I put the pin on the backside.
My truck will never tow, so I built everything to work together, not caring if it might not work with aftermarket stuff. If you want to use aftermarket stuff, you'll need to take that into account. also, be very mindful of the square tubing you use. towing hitches flop around a bit in regular 2x2 tube. fine for offroad-only stuff, but less than perfect for towing. try to get your hands on the receiver-specific stuff if you intend to tow.
