I am thinking of making an silver/black anodized or silver/black colored aluminum gauge "pod" that will look look like sort of the one in this post. It would have 2 x 60mm holes, 60mm fitment sleves, and mounting bolts.
As option, you could get 2 x 60 to 52 conversion sleves that would allow you to mount 52 mm gauges.
Price would be about 85-95USD shipped depending on wheteher you got the additional conversion sleves.
Let me know if you are interested and if you have any useful feedback
