Is there a reason you can't lift the engine with a floor jack underneath when changing the mounts? A block of wood between the jack and the oil pan has always worked great for me other than when I was actually removing the oil pan. In that case, I rigged up a lift that functions like the HF bar using a 2x4, a bed frame side rail (like angle iron - added strength to the 2x4), a bicycle chain lock, and a bolt/nut to mount the chain to the tow hook.
