Hello- My L785 is missing the power beyond valve and I haven't been able to find one. I ordered one through messicks but a few day later they called and said that it is no longer available from any new holland dealer in the US or Canada or either of the two obsolete parts sources they use. What is so special about this fitting? Anyone have one to sell? I'm wondering if it's something that could be made or improvised in some way. I haven't been able to even find a clear picture of one though. My machine is equipped with the aux. control valve and lines. any help greatly appreciated.
