I take a board on a jack, put it underneath the oil pan . You will have to take the shocks loose to do the mounts, so you can replace them if you want. Usually when doing motor mounts I replace the tranny mount also. I rarely ever do diff , rear subframe mounts. No torque on the mounting bolts just tight. Yes the 8 allen holds the motor mount to the mount arm and the two six allens hold it to the body. Good luck.
