They couldnt find a u joint that matched my shaft so I had them order me a new one. I will say, the shop I took it too was real nice and spent probably more time than they shouldve looking for a u joint. Definitely will use them in the future.
I think you are right. It seems to me that anywhere west of Nebraska has a pretty limited "used tractor and implement" market. Not sure why. I sold a tractor and several unused implements a while back. I barely had time to push the "post" button on Craigslist before the phone started ringing.
