Just use a common 2 wheel dolly. Put bellhousing end up and tailshaft on the floorplate. Use a ratchet strap just above the pan surface at back of bell to hold it to the dolly. Done 100+ this way.
Use a wheelbarrow and you don't even need to mess with the ratchet strap
I'm not knocking it one bit but the first thing that came into my head was the intro to dueling banjos.
You're not the first person to say that. It worked though.
