last I checked, it was about $500 to convert.

Only issue w/those is it probably takes several seconds at least for it to find the satellites after turn on.

No worky in tunnels of course.

An alternative if you swap in a Getrag 265 5-speed w/an electronic speedo output

Google:

https://www.speedhut.com/Speedbox.html

Drive Output Thread is 7/8"-18
1000 turns per mile


https://www.classicautoinnovations.com/classic

This one claims that it can be calibrated to any speedo. Speedometer cable connection: drive end:
Choice of 3/4 x 26 or 7/8 x 18


No idea of what you need to do to make this work on a Pagoda.

The fitting on the back of the Pagoda speedo head is 18 mm X 1.5 mm pitch

Neither of those threads is a match for this.

Thanks Gents,
Much appreciated.
Apologies for not having had a chance to look at the forum for a while. I have been and will be in the UK for a while(5 months)
Yes, I have looked at the three options mentioned above and I have realised that they might not quite meet my requirement, fully.
However, I’ll keep looking and I will certainly remember to purchase a 7/8”x18 fitting as well. Unless, I could find a speedo drive(mechanical or electronic) for my 265/6 Getrag.
Thanks again
