I tried a scissor jack and it did not work. I found two solutions that work. I went to Greg Smith Equipment and bought an air bag jack. It is basically a rubber bladder from a semi truck's suspension. It has a metal base and a metal jacking surface on which I put a hockey puck. Put it on the jack tray and air from my compressor inflates the back and voila, one corner, not the entire side of the car is lifted. There is a valve to release the air so you dont have to keep the air hose connected. They have a one bagger and a two bagger. Min height on the 2 bagger is 5-3/4" and it costs $249.
Another solution is an inflatable kevlar bag. Many towing companies use them, but were twice to three times more expensive than the air bag solution.
Good luck
