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.
I have knocked one down (FunHouse) while playing. Worse, it wasn't my game! Luckily caught it on the way down, but still felt like serious shit doing it.

As for the OP, Joe I think you have the cart before the horse. Put the games against the wall, and *move* the wall game. Now get a sheet of plywood, three door hinges, and some eyelets with hooks. Mount hinges to the plywood, then on the other end mount the hinges to ceiling joists so that the plywood naturally hangs vertically in front of the heads. Mount wall game to plywood. When someone wants to play pinball, lift the plywood so the wall game is almost touching the ceiling, and then secure plywood near ceiling with eyelet hooks screwed into the ceiling joists.
Quick, very reliable, and you can have your head bolts with no muss nor fuss. Should work for everyone that isn't 7' tall. Then again, someone who's 7' tall is going to have a hell of a hard time in Joe's basement to begin with!
