I just ordered the rear auxiliary hydraulic block for my B2710 so I could add rear hydraulic valves. It costs $91 + shipping! Seems pretty expensive, I imagine this being a steel plate with two through holes and two threaded holes, probably an o-ring on the back side. I'm hoping I ordered the right part, but I got it from Messick's and they always know what they're doing.
The 3 spool valves are only $350 and they are really complex, carefully machined components. I probably should have made this adapter myself.
