you don't need to pull the headers to see if the bolt is wrung off in the head, just use a small screwdriver to probe the bolt hole and see how far it goes into the hole, use your thumb as a depth gauge along side the blade. if the bolt is broke off, you won't go in far at all.
if not, then the blade will go in about an inch or more.
