Help ID My Steering Gear Box

[Matthew3c]

Still getting to know my Bronco... can someone help me identify the steering box? It’s plumbed to a Hydroboost system (included in pics) and all seems to work fine. Adding new engine with GM Type II pump and remote reservoir. Looking for any advice / knowledge on system... I plan to flush the steering box before adding new pump & reservoir. How much fluid will the new system hold?

Pic of the side would help immensely. I'm taking a stab in the dark saying it's the Delphi box that most of the dealers sell.

I'm guessing Delphi as well. Good box.
