John Deere 440 ID Backhoe - Pressure Relief Valve Assembly

I found a replacement valve assembly that had enough ports to include my pressure gauge and fits right into the side of the front bucket control valve assembly.
Cross RD12D SRDH Series Relief Valve

I ended up getting one from a local hydraulic shop that does hoses and other repairs.
