Kubota Box Blade Rippers

[TxRzrBk]

I have a 4' box blade that came with my tractor, it has a Kubota sticker on the side of it but other than that it has no markings that I can find. I was hoping to find a set of rippers for it but I am unsure exactly what will fit. Please take a look at the attached photos and let me know if you know what style ripper will work and if you can tell if it is a kubota brand box blade or something else.

I actually found a stamp on the blade that says Vassar 500-123 , so I guess it isnt a Kubota box blade. Anyone know where I might find a set of rippers for it?
