Need grip screws for an old Millitary

[recoil]

I'm working on a project on an original military and I am in need of the 3 grip screws. I called and the factory does not carry the older style that I need.
These are the screws that go all the way thru the backspacer and screw into the opposite G10 scale.
If anyone has a set or knows where I can get them please let me know

Thanks
