Just wanting to know what the diameter of the beetle speedo body is? not the bezel.

Cheers.

114.0 mm

ok sweet. hmm that where i went wrong.

I was 100% sure type 3 speedo was 115mm, so I bought a Porsche 912 tacho from the states to replace the spot of my speedo. hasn't arrived yet but I took out my speedo and its 100mm. (facepalms)
The tacho is 115mm. So I tryed to figure out where I got the 115mm measurement from? well I know now.

So I guess I will have a Porsche 912 tacho for sale latter. It will fit a beetle dash
