The setup from Rex was a Teleflex safe t quick or some such thing, it had the same 3 bolt pattern as the old one and if I remember correctly the rack setup had a 3 bolt mount also as we used the same holes when we installed the rack on the other boat. Call Rex they were very helpful and had answers for all questions. If you plan on keeping the boat I would go with the rack setup,it is noticably smoother, quicker ratio and no play at all.
