Do you want one that runs in the opposite direction the
rotary runs or do you want two gear boxes? One running in one direction
and the other running in the other direction? 

Must  both gear boxes  have  the same gear ratio?

If you just want one that runs in the opposite direction 
the rotary runs in I think the Ross 2.17:1 fits that description.
