OK guys, I’m part way through a fix (temporary or permanent - not decided yet).
As the picture shows I purchased some stainless steel tubing, ID 9.5mm; the only size I could find in my local area. Used a 10mm carbide tip drill and keeping it cool slowly expanded the ID to 10mm - who knew stainless steel was so hard! Removed the locknuts and placed the angled ball joint and push rod into the tubing. Interference fit to the ball joint shaft, firm push fit to the push rod.

Looks good (maybe better than the adj nuts on the original) but of course it still needs welding to both ends of the SS pipe, which will make it look like a bodge (which it is of course!)
Not entirely sure that the length is correct now and whether there will be enough adjustment on the back end if it is not, once welded! Need to remove the rod again and make sure the failed thread ends are touching (ish).
Managed to damage the rubber insert to the ball joint, stripping the rubber collar section that goes into the ball joint - Doh! It’s just a rubber washer now and will not stop crap getting into the ball joint. Guess it’s possible just to slide a new one onto the joint?
Any ideas for fixing this sleeve into place rather than a messy weld? Drill and pin may be a tad tricky. Epoxy adhesive?
Ideas greatfully received.
Regards, Steve.
