Yep, probably in there with lock-tite. I've never had to remove that bunny, but if I were the one tasked with the issue, here's what I would do. First turn the shift drum all the way counter clockwise, that way I could get rid of the extra tools. Then with a small torch, propane would be fine, I would heat the bolt head for a while. Then I would insert the torx bit, on the end of my impact gun, making sure it was turning in the right direction the first time, and then with a good amount of forward pressure, hold my breath, quit shaking and squeeze the trigger a quick burst. That would tell me if there was enough heat on the threads to loosen the lock-tite.
