1939 46C

Hello, I have the common issue with the worn out Torque ball on my 1939 Buick. In reading the various blogs it is a 1 year special for that year only. My challenge is finding somewhere that can reline the torque ball. I have tried all the usual Buick places online and so far not had any luck. If someone could assist with who to contact that could reline the torque ball that would be very help or has one to sell please get in touch. I have attached some photos of a refurnished torque ball that is what I want to get done. Thanks in advance for any help with this.
