Need YUGO mauser floorplate

I bought a 24/47 "gunsmith special" to fix up. One part it needs is a floorplate. I bought a replacement that was sold as a Yugo floorplate, but it's too long. It doesn't fit my M48 either.
Anyone have a floorplate or know where I can get one?

The replacement part has an E that looks like a backwards 3 stamped above the number 19, on the external side of the floorplate. The internal side has the number 12 stamped in the area where the spring goes, and the letter S stamped just outside of that area. Is anyone able to identify this floorplate?
