I've had an annoying oil leak coming from the speedo cable connection at the gearbox as the brass knurled nut is not deep enough to support the small seal that sits inside the assembly.Having been through my old spares,I have fitted a new cable which has a much deeper thread ( not brass) and supports the seal assembly too. When getting to the instrument panel however the cable nut does not fit on the right angled adaptor,so I've had to revert back to the existing cable along with its oil leak.Is this a special cable I need for my late HC?
Thanks for any suggestions,
Andrew
