unbelieveable, parts store is stumped, WTF can`t I find replacement shafts!
What I know -Or what the internet tells me, actually.
The third member I have was forged in 1972
The housing is known as an "old style" or "banjo housing
The dana 44 reasearches a little different:
From Mr. N

In 1976 the axles coil mounting cast brackets were slightly changed.
The front passenger’s side was made with the Panhard bar attachment
cast in to it. Additionally 1976 was the first year Ford offered disk
brakes as a standard option, although several late 75's have been
rumored to have disks. This axle stayed the same for 1977 for the
F100 and F150. The 1976-year also saw the release of the 3.00
gear set in December.
My dana 44 has disc brakes (always or was it changed??)
If the axles were both as is, as was, they have to be from a post 75 vehicle..hmmm, but the 3rd member apparently was built in `72..
This also from Mr. N:
In 1977.5 Ford’s new F250 axle now started to appear.
Previously, the F250 ran a standard rotation closed knuckle axle
(see reference pictures below.) This axle for the F250 44RS is
slightly different than the F100 & F150 offered in 1977. The F250
is a little wider than the F100 & F150, for the wider 8 wheel bolt hub.
The F250 also has 3" wide axle tubes with ½” thick tube walls, and the
axle has many different small changes from the F100 & F150 to include
larger brakes. This axle stayed this way until it changed to the Twin
Traction Beam (TTB) IFS system of the 1980 model year.
Plot thickens, my dana 44 is 3 inches wide, what does this mean? because it most certainly does not have an 8 lug nut hub, however, it would be easy to convert, right?
PS I don`t know how thick they are
BUT
In 1978 the 44RS had its largest change to date for the F100 & F150, which stayed with the axle until the transformation to IFS in 1980. Spicer changed the coil mounting brackets from separate cast brackets that held on the radius arms to a new design that was a single piece per side, with the tubes pressed into the ends of the casting. The center of the cast pieces does not have a tube that passes through it! (See Picture 14) Instead, a tube is pressed on both ends and welded together. This system came with outer tubes 3/8” thick and center tubes 3/8” or ¼” thick.
So my d44 has GOT to be a 78/79 axle as indicated by the cast pieces with no center tube, I recall researching this last year, and there is no tube in there.
So it would seem someone scabbed in an older rear axle into what was probably a bronco or f-150.
But the width is different? I don`t think the rear is wider than the front, track- width wise, but we are only talking about 3/4 of an inch here, which is what "they" say a 1973-1979 Ford pickup measured as. I don`t know if I would have noticed that, so it is possible.
I`m thinking that the rear 9 inch is a 72 F-100 axle, BUT my parts store has either given up or these axles are really not available.
Anyway, I`m trying to find info on 72 F-100s. It`s actually depressing to think that a vehicle built in my lifetime is so obscure these days, geez I`m old.
