I use 6 ton axle stands to hold mine up while pulling the engine/cradle. They are a lot taller than the smaller 3 tons ones I use for the initial lift. To pull from side I place them on the ledge in front of the cradle mount points. To pull from rear I place them on the bottom of the tub just in front of that area but be sure to chock the front wheels well as it's at such an angle it will try to slip (it doesn't but I would not like to be under there just in case).
