*I have the left and right rear sight slide arm anti aircraft wings for a Japanese Arisaka Type 99 rifle's rear sight. I need the screw that attaches the wing to the sight. Does anyone know who might have a couple of these screws that would work? I know this is a very small action but these screws have special treads and without them I'm stopped from mounting the replacement anti aircraft wings to the sight. I've tried numrich and jack first...no luck. Even the local hardware store can't find something that works... Any help you be really appreciated.
