I will be going to my friends house shortly to help him remove an axle shaft from a 10 bolt rear with a gov-lock. I have never removed one from a gov-lock, only an open diff with the c-clips. He says he can't figure out how to remove them, he says some type of "I" shaped metal block is in the way. How do they come out? If ya'll tell me the trick he will think I'm real cool... 

I just did mine about a year ago. Now you had me thinking, And now my head hurts.
I'm to tired to think, but I remember it was easy after I pulled the cross pin. Took me about 5 min. to figure out.
