Trailer axel hubs that have a 2 3/4 bolt to bolt center. They have a square mounting bracket that is 3 3/4 square. The bolt pattern for the bracket is 2 3/4 by 2 3/4. See my pictures for more detail. Thanks for looking. Mike
I will get the pictures very soon sorry about that. I will be selling some hubs that have a pipe on one end.
