Finally I got home from work and straight in the garage to start rebuilding driveshaft cv joint after welding up hole in cv joint cover,never done this job before so it was a learning experience and a bit of a puzzle to get it together in the right orientation,it’s a bit like trial and error,my advice is don’t force anything and assemble the opposite way to what seems logical lining up the grooves and bearing spacings is wrong.Fitting on the car went ok although it’s a bit nerve racking hitting outer cv joint to fit shaft inside the hub.
