Ended up drilling them out. I got an 1/8" and 3/16" left hand bit but they just ended up drilling through and never grabbing. So I went through with the #7 and retapped the holes. Well two anyway. I was able to knock it off without drilling the last one all the way out and now I'm going to put it in the drill press to drill out and tap just like the others.
Does the end of the crank look funny? It looks like someone put the pto together wrong and it was hitting the crank and it's just galled up, but it's really rough.
