looks like the one I recently dealt with. I am no expert, but I suggest that you talk to an overhaul shop about the possibility of "re-clocking" the aft portion of the governor to a more ideal position. Not sure that can be done with that particular governor, and you want to pay attention to which way the arm is spring loaded to High RPM... I think that can be modified as required.
The one I dealt with had the same arm and was oriented one set of bolts ccw, looking from the rear. That was advantageous for a gov cable coming from the right side of the aircraft.
If you clock your gov two sets of bolts ccw, 180 degrees from current orientation, with the arm on the bottom, you could approach with the normal RV cable orientation. Not sure that a standard Vans bracket would work, have not gotten there on my project.
Others will have more knowledge about this than I.
