Mark V action mounting screw

[tomsrob]

Does anyone know where I can find one of the screws for mounting the action into the bottom case? (one of the four on the underside) Or anything that would work? By luck I found an old push button switch that had the same threads to use temporarily while I worked on the action but I'd like to find a permanent one for the owner.

I would take one that you have to a hardware store and match it up. May be easiest and cheapest option.
