Anybody heard of a short R5 floyd nut?

[EVHwannabe]

I bought a neck on ebay that has a 1 3/4" wide nut, but the Floyd nut that came on it is shorter than the normal OFR R5 (which is one of the taller ones). When I try putting an OFR R5 on it it is WAY too tall.

I couldn't find any reference anywhere to a floyd nut that is 1 3/4 but is short.

Do other knock-offs make these? It definitely does not have any markings on the bottom - no name, no "r" value, nothing....

Thanks
