I bought 3000psi cylinders from Northern Tool. I bought a 3 spool valve from another company but don't remember where! I plumbed the "in" on the valve from the lines that went to the rear lift cylinders. Tee'd them into one line. Then the "out" of the valve to the dipstick for the hydraulic fill. I drilled and taped into the side of it with 3/8 npt. Then the first valve went to the lift, second went to the dump bucket, and the third to the rear lift arms. For this all to work the hydraulic lever on the steering column has to be up to "turn" the pump on. Its not as nice as a live system but it works. I can take specific pictures of something if you want. Any more questions please ask.
