Kuryakyn halo headlight ring

Has anyone tried mounting the new Kuryakyn Halo headlight trim ring to a 2003 Big Dog Chopper? My headlight measure 6" OD but the Kuryakyn comes in either 7" or 5-3/4". Doesn't make much sense to me that the 5-3/4" would fit in the 6' shell but does anyone know for sure?

:bang:
