Quoted from Pimp77:Head bolts are totally unnecessary. Hell, even the latch likely isn't needed. The head sits pretty darn solid with gravity. The head has to lift up and be pulled forward to come down. Latches are fine and totally enough to keep the head in place. I don't think I've EVER bought a game that had them installed. Seriously, has anyone seen one just fall down while playing? Really, serious question. Doubtful.
Interestingly, I've only bought one game that didn't have the bolts installed, but then again, all my games were bought from old timers that were at least in their thirties.
