OK appoligize this is borderline bike usage, but think worth mentioning. Tried to find a case for a typical meter for car. Found in auto store a $3 cup holder ash try. Black with chrome top. Just pull off the top lid and the middle metal funnel ash collector, is held on with four bent metal tabs. Bend tabs and remove, this leaves a hole 1 15/16 hole. Plastic is easy to file out. A little long but beautiful dash gage holder. Merry Christmas.
