I usually hook a chain up at 3 points, the top PS pump bracket bolt, then a bolt on the opposite side of the head next to the intake mani (I think I thread one of the frame-to-front-bumpstop-mount bolts in there). Then depending on if you're hoisting the engine only or engine + trans:
Engine only - One of the lower distributor bolt holes with a distributor bolt.
Engine + trans - There's a steel bracket on top of the trans.
BTW I recommend leaving that rear trans mount on the chassis and loosening the 3 bolts from the engine/trans.
