SW20 axle end threads.... 19mm and 21mm?

[RomanV]

I folks.

It would appear that my old axles have 19mm o/d threads on them, and my new axles have 21mm threads on them.

So the nuts that secure the axles to the hubs obviously dont fit.

Does anyone have an idea on which SW20s came with the larger threads on the end?

As I need to source some.

probably same deal for my ST165, I bought new halfshafts and they had larger threads, I found that off AE101 fitted perfectly (I had them luying arround)
