They had the Updated production hinge at the SEMA show. This new hinge was a very stout design. The door opened and closed smoothly and was very stable through out the arc range. I spoke with the designer, he told me this is not the same hinge that they took to the rally. He was against taking the early hinge to the rally because he did not feel it was up to his design expectations and didn't want to get a bad rap. That being said it is still too expensives. Now that they have the casitngs I would think they would want to sell some of these things so I would be in for a group buy. For the record there is a lot of work to put these things on . Fronts fenders must come off as well..
