Welcome to TBN. I see you are also in NC. Are you familiar with an outfit near Winston-Salem called Leinbach Machinery? They are a treasure trove of ag supplies, implements and parts. They sell hardened, weld-on replacment tips for box blade shanks and toothbars. I bought several a while back to replace worn ones on some of my stuff. If you have a local welding shop available, they could probably fab up the stub and add it to your existing toolbar. Then you'd just need to add one of the hardened Leinbach tips.
