Is there a scale on the back of the rod, perhaps in the upside down orientation?
If there is, maybe you can simply flip it over if the securing hole is only at the top....
Otherwise, the numbnut at the factory stamped the rod angles upside down on the metal.....
Use an angle or a protractor to set it to 22 degrees and fine tune using drift alignment and then maybe mark it with tape or scratch (eek) a mark where home latitude is....?
Cheers
