Most mounts will have enough adjustments or allow for that I would imagine.

Magnetic declination can be quite a bit larger than most mounts will be able to adjust for. It's a hair over ten degrees at my observatory, and there's some source of local deflection that seems to add a couple more degrees.

Magnetic declination

Go out at night and line up your pier with the North Star; never mind the compass. Drive a pair of stakes such that the line between the stakes lines up with Polaris. You can even check a chart before you go out and compensate for the small difference between Polaris and the north celestial pole. You should have no trouble getting within a degree just by eye.
