Well I took the diff tag off the diff and let it soak all day in some degreaser and now it looks new and i can read it and i think it gives the information needed to determine what year and what cut the axle is. The tag info is below.
3.50 D9TA ACB
610067 - 2

Hey the thread is a little old but did you ever figure out which vehicle the axle was from?
I have the same axle of unknown origin, with a #610085 number on it
unfortunately it is not listed anywhere
it is 65" wide and seems to match all your descriptions and yes it is reverse rotation (HP)

Eh, I dunno looks high to me, I`m actually having trouble getting parts for the 9 inch I got with my d44. unfortunately all I saw was a frame with two axles on it when I got them. The internet tells me my 9 inch was never in any vehicle, my d44 code doesn`t show up in any code list I`ve seen, all I know for sure is the third member was cast in 72, but I can`t find a 72 with 65 inch wms to wms.
Anyway, thought I might get some ideas if my d44 was Identified, perhaps it was an old axle that was changed to disc brakes later or else the older 9 inch was swapped into a F-150 or Bronco. Or the 3rd member was swapped in..
I tell ya, sometimes free axles aren`t worth it if you don`t know where they came from!

Try not to concentrate on the stuff on the outside. If you have troubles identifying parts by eye, then simply remove the inspection cover and read the numbers on the ring gear.
Really does not matter what it came from as long as it works. Using the numbers on the ring gear will guarantee that you get replacement parts that fit. The same thing goes for bearings and seals. Every bearing and every seal has a part number that directly relates to the demensions of the said device.
Axles can be measured and splines can be counted. finding parts is not too difficult.
Over the years many guys make modifications that may use alternate parts that would make the numbers from the restoration guys useless.

The D44 was easy to get parts for, but everyone tells me the 9 inch shaft length NEVER came 28 spline, only 31. I`ve had to bring a shaft into the parts store to prove I`m not an idiot and they still can`t help me.
I`ve got a 28 spline traction device in the third memebr I`d like to keep so changing over to 31 is something I want to avoid.

They seem to be all over the place here.

While I will admit having identical lengths sounds odd, I would not hesitate to use two from one side.
I.E, two left side axles for example. Pretty sure somebody may have done this with yours.

31 spline upgrade is an option I am looking at, but the traction device is a detroit softlocker and I can`t seem to find a re-build option for them. I could sell and re-buy, but I`ll lose money for sure. most likely I will have a set built.
But the mystery would remain unsolved, and that drives me crazy!
