Steering shaft part? ID assistance needed M915 M916

[Suprman]

I have a few of these I believe they are updated versions of the M915 M916 and other AM General semi truck steering shafts. The part numbers dont seem to cross to anything in the TM's that I could find. Dimensions to the M915 version are about the same. Can anyone shed any light on this?
Thanks
Will

It is probably off a current use truck. Thus secretive.
I can't find it anywhere, with 42 of them I hope you can get creative!

PTO Shafts? Maybe a PTO warehouse can use them?

It looks practically identical to the M915 M916 M920 steering shaft I am thinking its some type of upgrade. I have a big pallet of them.
