Don,

Those were the bearings I ordered last month. Their outer diameter turned it to be a fraction larger then the inner diameter of the torque tubes. I solved the issue be taking a piece of a wooden broom handle, mounting it on the end of a drill, wrapping the broom handle with sandpaper and reaming out the inner diameter of the torque tubes. 

I used normal washers as spacers and two large area washers against the center hinge to make sure the bolt could not pivot from side to side.
