I bolted mine to the bottom of the frame in the front.
I had to move the bumber up as high as I could so that the hook would sit flush, and I still had to grind a little notch in the bottom of the bumper. I also had to grind approx 1/8th in. off of the tang of the hook so that it would fit in front of the plate that holds the anti-sway bar in place.
There were two predrilled holes on my frame, and I was able to use one of them and had to drill another. I didn't take the time to see if I could get a set of hooks that had the exact right dimensions that would be a direct bolt in/on.
A 3/8th in. plate placed under the frame would have lowered the hook enough that I would not have had to cut the bumper. I could have used a short stack of washers, but wasn't sure if that would predispose it to failure.
I don't know if there are alot of options out there, I was in a hurry up mode, and just got the first set I could find and made them work.
Have fun,
joe
