I bought a set of those arms separately and should be installing them by the end of the year, They allow for a front steer without flipping the steering arms and give the ability to adjust as well,they are a well built piece
I bought the arms from this site http://www.gofastmopars.net. He make the arms for a front mount rack that eliminates the bump steer as it fixes the issues. You don't need to flip the arms when doing this, plus they were not expensive.
It is not a conventional socket, it is a square cut socket made especially for mopar ball joints, if I remember correctly there were 3 sizes. I attached the pics of the ones I own, these are Snap on sockets
