help with a plow point

[sogahunter]

I am looking for a point that looks like a middle buster that has been cut in half. you can use these to make a bed and to cover potatoes after they break the surface the first time. I have a set now but looking for 2 more for a 2 row operation. any help would be greatly appreciated. It looks like you cut the middle buster in half and then swap sides with the wings so they throw the dirt up in a hill. hope this makes sense.
