The only thing I might add is that what I did is put the front end of the car on ramps, and the back end of the car on large jackstands (6 or 8 ton, I can't recall.) When you measure the jackstands, it doesn't look like it will work because the engine is taller than the stands, but you have to remember that the car will be at an angle, so the back of the car will be much higher than the jackstands.
I'll have to post a picture of my car in the air. It will make a lot more sense than my explanation!
Good luck with it!
