One last thing!
What I should have done when I had the gauges out of their cases, is to strip off the white reflective paint inside them and respray. The paint was flaking badly all over.
Not doing this meant that when I had the gauge upside down, and was hammering the bezel crimp, a couple fo flakes worked their way down (somehow) onto the glass. I am thinking that maybe they will vibrate off the glass while I ride but that hasn't happened yet...
They are small so I will get over it if they never disappear!

By the way, I put LED pilot bulbs in place of their incandescent and I can actually read the gauges at night!!
