used a four foot piece of angle iron bolted to the flywheel and a 3/4 breakerbar to a 1/2 inch 54mm attained from amazon. the breakerbar is three feet, i believe, and i used the lever off my floor jack as a cheater bar. Kind of a pain to get everything together, but it had to be done. Hopefully one day i'll buy an impact wrench worthy of the task. Now to tear it down.
