Just trying to figure out why this is happening, I am pretty sure this is the first time there has been an issue like this.  The plates have measured parallel now you can also check to make sure they are perpendicular to the rails with something like a carpenters square. The misalignment is at an angle (closer to one rail) suggesting something like this.

The bearing fit, the bearing is jut there to hold up the coupler, no need for clamps or anything.
