It's Just a regular large bolt.
A 2ft breaker bar?? Feck! i just used a foot ish long adjustable and a similar length ratchet. Few bruised knuckles though when I was bouncing all my weight on them and then it finally loosened! Was a bit worried I was turning it in the wrong direction it was so tight!
