Make a mounting bracket out of 3" or 4" wide x 1/4" flat stock just a little bigger than the size of the valve and it's DO3 subplate. Drill 2 holes in the flat stock to match those just below the loader valve on the right loader tower. Mount the valve there. That is where WR Long valves mount. You will need a short hose section to go from the loader valve PB port to the DO3 subplate inlet. The hose that connected to the loader valve PB connects to the DO3 subplate's outlet.
