if you say what specific measurements you need i can measure and post here. I've done an electronic speedometer with leds bar, I need to replace the old one with this. So with the internal diameter I can finish the pcb layout. ^^ sorry for my bad english. OK, just measured one. Each face is 82mm in...

mmh ok but I need an accurate dimension...to design a pcb. no sketch or drawings here?

thanks

I need to know the measure of the internal circumference of the speedometer, can someone help me?

maybe the Z2 model, like this:
