Arai drum - what thread on the wheel?

What is the thread size, pitch and direction on the hub for mounting an Arai drum brake?

I have an idea for something a little different to mount in the same location, and would like to know this information to be able to finish my design.

Thank you

I don't know the specs, but I believe it's the same as freewheel threads, so you could look that up.
