Good question JM, After posting that last night I went for a nice search, I think what I wrote yesterday was wrong , I found a post from a while ago. As I do not know the exact age of the axles I am thinking this may be the answer having looked on the parts catalgue.
Though I may be wrong.
If it does NOT have a drain plug from the hub then it will need the swivel kit with chalice DA3178G. Post KA930456

Am i right in my thinking?
I will also go out and search the axle code, although I still have not found anything to confirm axle code against swivel kit ( will have to search harder ) hoping it was not mixed and matched by the PO. Is there a way I can identify which swivel kit is needed ? either by spline numbers or something else.
Cheers
