They look very nice. At least the kph M model is hard to fault. My only comment is that the dial faces and surrounds on my M gauges have a bluish grey colour. What he's got pictured on ebay look almost black. That may be just an artifact of the process of supplying those diagrams and posting on a website. Maybe the actual pieces are closer in colour.
Would probably pay to ask for a photo of an actual item before diving in. If they are significantly different to the outer surround of your M model gauge cluster they'd look pretty odd.
