Arca-Swiss plate for Horseman LE?

[OdDoFl]

I have a Horseman LE 45, and would like to use this with my ball head which has a clamp from Really Right Stuff. Do anyone know about an Arca-Swiss type plate that will fit on the Horseman?

Arca Plate f/Horseman LE

The best plate for this camera would be a universal in either 1/4 or 3/8 screw.
The camera is a heavier monorail type and needs a longer plate or foot,
So the 80mm plate is best.
