On the 100mm Smiths Classic Tacho, I assume that this is the diameter of the hole, correct? Can you advise the outer diameter of the chrome bezel. I am trying to match the existing Smiths Speedo gauge in a Ginetta G4 vintage race car.
That is correct, the body of the Smiths Tacho and Smiths Speed is 98mm the outside of the bezel is 103.4mm.
