Unfortunately, I don't believe that your "U" shape fitting is available anymore. Our 23-134 pivot bracket might work, but it will depend on a few factors.
If possible, I would like to see what type of pin locks into this fitting. Also, are the nylon cylinders part of a another fitting?
Your top pivot appears to be an older version of our 23-182. This should fit in the new style Johnson pivot bracket, the 23-134. The nylon bushing is no longer used by Johnson for their bottom pivot bracket, though. The bushing is now metal and part of the bracket. You can review the photos on its store page/
