The kit that I bought included bearings that I did not need, 1 ball and 2 sets of rollers.
They offered to refund only 1/2 of what I paid claiming that some industrial versions of the T96 needed those certain bearings.
So what--I bought a kit for a car!!
Additionally, I needed an extra bearing for one that they did supply and I found it locally for 1/2 of what they charged me.
