How many are using the factory amp meter

I used a Sunpro voltmeter. Took the guts out of the housing and mounted it in place of the ammeter. It was almost a direct fit. Just a little grinding, filing where the studs go. I had to do some minor trimming to the original ammeter face to get it to mount on the new gauge. The picture shows the new gauge with the engine running, and 13.8 volts reading on the gauge .The only tipoff that it is not original, is the needle is a little brighter red.
