Brake Master Cylinder Mounting Nut Size

I found the part number 382802, but can't find the thread pitch and size anywhere. Anyone know what it is? I lost both of them and need to get new ones.

Thanks y'all. It looks like the reman master cylinder I got has different size studs. The studs mounting to the firewall are the same as factory, but the master cylinder studs are 10mm-1.5. Back to the hardware store....
