You will love the B&W and love there staff even more IF there is any reason to contact them. Very good people there! A friend of mine bought a truck with a frozen B&W in it and picked the entire truck up with his track hoe trying to get it out.
A little penetrating oil and a couple of jacks and a setup similar to what you made, and it was out in about an hour.
