1967 f100 4x4 power steering box id

[Diveboss]

I’m looking to replace the power steering box on my 67 f100 4x4. I am unsure if this was a factory power steering box or if this was a later modification.
I can’t seem to ID the unit so I can get the proper replacement box.
The metal tag on the power steering box is SPA AX 76K 27P (unsure of the “P” as it is partially hidden under the bolt.
The cast stamp on the cap is C6AP 3580-A2

Any help would be greatly appreciated!

The drawings might help ID what you have?

The difference in PS variations also might help as it seems few 67' came with PS, (was an option in the early years):

I'd also recommend reaching out to our member Jerry, (67Mann) here as he knowledge on the 67' and being pretty active here still might help.
