We have at the present 2 units [ATTACH=CONFIG]38564[/ATTACH]left. If anyone is intrested.
Cheers Glenn

The new Stag Mk2 has a black bezel as per Stag and uses an induction pick up.

This kit is available directly from Holdens http://www.holden.co.uk/displayprodu...&pCode=070.190 where they explicity mention a sensor has to be fitted. I'm guessing that as their other gauges are made to the original Smiths blueprints, then the the black rim could be transferred. The sensor has to be placed very closely to its source (within 1-2mm) so any eccentricity here would be a disaster to the sensor. The gauge is available in Magnolia too. They have inbuilt illumination that you may want to change the colour of to retain the green glow of your other instruments. The total cost is a bit eye watering.

The one in the link is the generic Smiths one and slightly different to the one we are talking about which is specially made to the Stag Mk2 style, and which also comes with the green lighting.
It runs fine using the rear prop-shaft bolt threads (slightly longer bolts fitted) at a gap of 2mm. Any runout here greater than 2mm would be unlikely and felt throughout the car. Just taken this photo of the bracketry for the sensor:

Having tested the speedo against a GPS speedo app on a flat, straight section of road at 70mph there is a difference of 1mph (speedo high) and the needle is rock steady. This error could be dialled out by adjusting the input calibration number slightly, but it is close enough for me. Closer in fact than my German daily driver.Last edited by DJT; 16 October 2016, 12:49.Dave

Can't really see the point of transferring the old black bezel when Glenn's offering has a new bezel, is made to match Mk2 instrument and is similar cost.
Placing the sensor should not be an issue, if you have that much propshaft eccentricity you have a bigger problem!!
Yes it is expensive but solves a problem with DIY ZF conversion, and solves speedo gearing and cable problems.

I use a Transit crankshaft sensor which I drilled through the diff nose subframe to fit when it was off the car. There is a slight offset due to the shape of the diff but not enough to affect the sensor.
