Polar Alignment With no DEC Markings

I just got a used GM-200 and this is the first mount that doesn't have any type of ticks or markings on the DEC axis (and there is no polar alignment scope). To do polar alighment, I am in the process of drift aligning. Once I have this nailed, my plan is then to move the scope to the location of Cel North and mark the mount on the dec axis to "ZERO". Does this sound OK?

Zero degrees declination is the celestial equator. Celestial north is 90 degrees north declination.

To help locate zero, you can sight a star near the celestial equator. zeta Aqr has a declination of less than 2 minutes north.
