As shown in the CAD drawings of the bezel the OD of the AWE gauge was 44.6mm (body of the gauge) and the lip OD is 47.3mm. I am not sure how they name gauge sizes, i.e. "52mm gauge" if that is the body of the gauge? What ever gauge is being used the dimensioned must be confirmed/modified for the bezel to house/seat the gauge properly. I worked off the AWE gauge for my the dimensions on the bezel.
