I went out and removed the rear right hand swing arm boot - these are much easier to remove than get back on.
And I could see the end of axle - mine does have the stones - you can just see them in this pic taken from directly underneath.
Looking back at Dan's pics and noting the relative size of the the yoke and the size of the actual driveshaft, clearly his are not deigned for stones but mine does have them with the of the stones being about the same size as the round protrusions on Dan's shafts.
So clearly there must be two styles of axle, one with the round protrusions that Dan has and mine with stones - I like Dan's better. Can someone please clarify.
Anyway - I had the typical issue with the square stone in that the flat sides are supposed to fit into the slots as shown in Dan's pic above but as usual when the axle comes out too far the stones twist 45 degrees so they will not longer fit - they still lock in but the axle cannot go home.
As the axle was generally in the correct position I was able to use a screwdriver to move the stones to the approximate position and the axle went home.
Sounds easy doesn't it but I can tell you I must have tried the mentioned process about 100 times before the planets all aligned and it all went in.
So the lesson for the day is do not let your axles slide out a bit and your stones will get misaligned and cause you no end of grief - unless of cause you have axles like Dan's where I am sure they will just pop straight back in.
