I've got hype bindings on an O'Brien, I just went to an ACE harware store and bought the four screws I needed, cost me a whoppping 85 cents for all four. Just mark on the screw with a permanent marker where the excess screw starts, just screw it all the way in and mark the part sticking out, then go to a hardware store ACE, Home Depot, HQ, or whatever and tell the huys what your looking for and show them the screw and they'll hook you up. Good luck.
