Update - after my seat reupholstery adventure, I got back to finishing up the steering rack.
I made sure to assemble this right on the crossmember, to make sure everything fit correctly for later installation under the car.
I painted steel pressure lines rust-proof black, and part of cylinder gray - each after removing corrosion. Also replaced feed and return lines with new ones (needed to bend some of the steel tubing to match the old line profiles), as well as the compensating line.
At any rate...here is one "before" photo, followed by two "after" photos, with the finished rack mounted on the cross member. (Will likely leave it mounted for final crossmember placement under suspended engined, prior to securing engine with mounts):
