How much "assembly" do you have? There are only a few places to attach bolts through chains, such as where the PS Bracket support bracket mounts to the head above the manifolds.

It's diagonal partner would be the clamp boss at the back of the head just above and to the rear of the large core plug.

You should invest in an engine tilter to make it a lot easier unless you choose to install the tranny after the motor is in place.
