Here`s a few pics of the two axles, I have a feeling the supposedly HD GKN`s are actually STD salisbury, they all measured up between 1.175 and 1.190, my origional ones also had a few markings as well, that someone might reconise.


Longer splines VS raised portion

Markings

A few more markings
Any ideas of what they are, STD or sometime better?
Any thoughts would be greatly appreciated.
