Here are some answers to your requests:
I´m sorry, but I do not know, how the fixture is working but I will ask him (I didn´t see it cause he did it in his lab when I was busy with my nav)
The rings are clipsed into the frame and fitted absolutely perfect. I bought them in ebay some months ago for around 15€
My friend offered me a complete ///M function as for the lighting of rpm, too. This would have costed 100,-€ more but I thought this would not be necessary. So it is not lighted at all now.
At night the speedo looks great, the red needles make a special light, but well fitting to the rest of the interior.
The adaption of the speedo has been doen also...of course... the scale is different with the speedo.
But as I heard some times from him, changing the speedo with the needles is very tricky, you can ruin them very fast!
Make some pics in the night and post them the next days.
Thanks that you like the mod.
