Product review (5 stars): so it wasn't a problem and was a perfect fit. But
The item was exactly what I needed - but not exactly what was presented in the description. The three screws that go into the ball shaft were small bolts that had very small washers. The ball shaft holes were threaded to match the screws that came with it, so it wasn't a problem and was a perfect fit. But, it had me worried that it was the wrong item.
