My ST becomes a project bike...

I still have a failed tachometer somewhere in my garage. It appears the space in the white dashboard is the mirror of the speedometer, so a measurement from that should be useable. I can't estimate how long it might take to find it, but I'll look.

I have a good picture of the back of the dashboard

thanks, but I 'm looking the measurements of this white housing from inside, can't imagine how to estimate them precisely

thanks too, it won't help unfortunately, unless you accidently find this white housing )
