With thanks to Lyn for information on the conduit threads, it did not take long to find both dies on the net. These arrived on Friday but I did not have the right sized die holder. I borrowed a 2" holder and after a few minutes on the lathe was in business.
The conduit out to the tail lights is now complete. I did have this going through the gap above the gearbox, but fortunately checked my original photos and realised it goes behind the seat back. I note the cleaver use of joiners in the original conduit to let you instal it in sections and feed the wire through as you go.
Only a few more broken bolts to remove and a bit of panel beating and it's off to the sandblasters. Yay.
And I thînk I've sorted out this photo rotation business.....
Nope, they still randomly rotate
