Kubota M5700 3 point leveling box

[PineBrookFarm]

The leveling box on my m5700 looks like it was hit by something from the previous owners. I took it apart and it damaged beyond repair. I need to get a new one but the part from Kubota is like $600. There are lots of aftermarket options for other tractors for $80-150 but I can't seem to find one for this machine. Anyone know of a solution here?
