That's not a bad idea! And air assault btw
I thought I'd give another option for the Hi-Lift mount. I too used the exhaust clamps but I used a piece of angle iron that stretched across the exhaust clamps and then drilled two holes on the angle iron put a bolt at each end and slid the jack onto the bolts then used wing nuts and washer to attach the jack. That way you don't need tools to remove it. I still only had $20 in the whole setup. Just another option I thought I'd throw out there.
