Did you bench-bleed the master cylinder before you installed it?
I made an adjustment wrench for the front steering box adjuster out of a piece of 3/4" X 1/8" flat stock bent into an "L" with the foot about an inch long to fit into the space. 3/4" wide stock just fits into the depression of the adjuster (which looks like a huge allen wrench socket).
For that HUGE nut on the front of the box I use a plumber's drain wrench. Looks like an adjustable crescent wrench

The adjuster on top of the box is pretty straight-forward - wrench and screwdriver.
