Be patient on a response back through email only. I bought this a few years ago and never needed it. I don't know what it fits but I think the guy had a Ford tractor with a backhoe on it. I didn't at all pay attention to what it was, could've been a 9n 2n 8n or a 600-800 series tractor. Not sure of the brand of the backhoe either. The diameter for the pins is 1-1/2" The gap where the lower pin goes through is 2-1/4 upper is 6-1/8. Cutting edge is bowed but good shape otherwise. I usually only check email once a day but not on weekends. Cash only.
