Mini truck power steering box?

[Code54]

Looking to rebuild power steering box but not 100% sure what came on this 79 FJ40.

Is this the "mini truck" power steering box? If not, any idea what it is?

Also is the mini truck PS the box for the 1981–1985 4WD pickups or 1984–1985 4Runners?

Thank you!

From another thread: "1979 -85 4wd truck and 84-85 4runner- All of the boxes are all the same except, the earlier steering boxes have a smaller port"

There's a good thread on here somewhere about rebuilding them. But it does take special tools so I never have.

Someone will be along to correct any of my errors above...
