I decided to mount my Hi-Lift on the front bumper for my most receint offroad trip, and I think it turned out well. I used the foglight tabs to bolt the jack to.
It held fast, and only cost a couple of bucks at the hardware store.
I used a (Master?) Cobra lock on mine and it works great. Mind you, I mounted mine between the roll cage downtubes so's to protect from the corrosion issues we face here in the infamous PacNW rain.
