Which 15mm bracket for this Epic/Scarlet bottom plate?

[Gabriel Gettman]

Does anyone know what lightweight 15mm bracket will work with the spacing of the threads on the front of this bottom plate (pictures attached)?

Looking at photos of various bottom plates and brackets, I can't see any standardisation, but maybe I'm wrong!

Thanks for your help!

I don't believe there is a standard for holes that mount a 15mm lightweight because they all mount them differently/
