Depowered Rack - Hydroboost

I  was hoping someone could point me in the right direction.   I decided to depower my steering rack as I have been dealing with a leaking rack far too often and have had to replace it three times over the years.  I assumed I'd be able to simply block off the high pressure line running to the rack from the mustang hydroboost so I could keep my brake assist...but apparently thats a no go. Now I am looking in a manual brake option. what do you think is the easiest way to do this to get me rolling.  I hate to lose the hydroboost brakes but I dont know how to keep them with the manual rack

What is the best way to get back to running with manual rack.(depowered)

Run the high pressure line back to the reservoir. It won't be under any pressure, it just acts as another return line.
