I've got a 1982 Series III (RHD) that I'm replacing the clutch hydraulics in (uses the same as the early Defenders). I've got everything except the metric male fitting from the 1/4" tubing to the clutch slave. I know it's an ISO bubble flare on the tube & the fitting is metric with a non-threaded lead, but does anyone know what the actual size & threading is? Near I can guess is that it'd be a 12mm x 1.0 like this one that FedHill sells.
