I did the same thing to mine. Gotta make sure you seat the rocker in the pedistal correctly. Otherwise when you torque it you will break the pedistal.
That's the name of the part you are looking for by the way. Pedistal. You can get them from crane, but you have to buy 16 of them in a pack. About $23 bux if i remember. Let me know if you can't find them and I can post up the part number when I get home from work in about 8 hours.
Well, make that three of us. I just broke one of mine tonight. Calling Crane in the morning. Just one more thing to have to spend money on. I think mine was broken from the beginning (used parts ) Anyway, will keep you all posted.
