most that have jacks are just behind the engine on the frame. Go check out a rig with the auto jacks and it will give ya a good indication of the mounting points. Big problem will be having to lay on ground to crank up/down as the frame is a way under the low hanging running boards if installed. Easier might be to use a small bottle jack with a U shaped channel to fit the frame (1 ea side). Small 2t jack would work I think just have to fab and have welded to the top screw, still need some blocking on bottom to rest on.
