Hi Richard,
I got a phone call this week that the gears and adapters are ready. I plan on collecting them coming week. The machine shop told me that the second production run, if ever needed, will be costing more as it was more work than anticipated. But they stuck to their quote even do they lost money on this batch!
On your speedometer there is a little conical gear. You need an adapter that has a matching gear inside and slides over the speedometer. This adapter has a 90 degrees angle and the oposite side has threading for your cable nut.
I bought one of these adapters from Brian Ashbury, it is his picture, but discovered that my speedo already had one. There for it is surplus to me. If you need it you can have it at cost.
Cheers,
