Hi Shane. The hinge points towards the South Celestial pole but see my pic for explanation re; your base board etc.
Having made a Curved Rod Tracker, I made a wedge for my latitude which sits flat on the tripod.
This tilts the base board to the correct angle.
I made another smaller wedge & fitted the ball joint on an extension here. Gives a lot of movement for the camera & assists in getting 'CG/balance' correct. (Second Image).
