ignition switch threads for the trim ring

[Harpo]

Good afternoon everyone,

The trim ring for the ignition switch threads on to the ignition switch as most of you know. Does anyone know the thread dimensions? Diameter & pitch?

Thanks

David

Photo is worth 1000 words hopefully this will help explain what threads I'm talking about.

According to the internet the threads are M28-1.0 so it must be true

I make the early 911 bezels and can confirm that the threads are M28 × 1.0 6H.
