Need the cast aluminum collar that goes on top of the tripod and which in turn has the CG5 EQ mount screwed into it.
It's the round black/gray part that is attached to the tripod legs. Mine has an "N" for polar north on it and also has a prong for RA adjustments when polar aligning.
Have (more or less) permanently installed my original collar on a pier and would like a replacement for use with tripod when travelling.
