I recently removed the speedometer in my ’62 and took it to a local shop for a rebuild. There are four screws that hold the chrome bezel to the metal case. (red arrows in the picture below) I also have an extra bezel that I purchased from a forum member. The extra bezel did not have any of the four screws so I removed the screws from my original speedometer and tried them in the extra bezel and found that they did not fit. I tried my standard thread gauge on the threads and could not find a match. I tried a metric thread gauge and the 0.8 mm fit perfectly, and the diameter of the screw measured 3.3mm. I compared the threads in the bezel holes (second picture below) and noticed that the threads in the original piece had 6 vertical “cuts” around the circumference of the screw holes (the threads on the right in the picture). So, does anyone know what size screw is supposed to be used here?
Thanks,
