Sanman,
I am hesitant to answer that question without seeing the setup you have, any chance of posting pics of the loader mast?
I did not pre-plan the location of the diverter valve, I ordered it and then when I had it in hand, set out to find the best, most out-of-the way place to mount it. If you are sure you are going to do this, go ahead and order just the valve.
Good Luck
