Trying to find the thingy that the boom swivels on. It's a white piece of plastic about 8" long. My booms are 18 years old and the booms don't freely move. There was a company in TX that made these for everybody but I can't remember their name.
Mac I know exactly what your looking for, the plastic bearing insert that the boom swivels on. We needed some a while back, I think we used gray 1" PVC pipe.
