I made a mistake on my earlier post. I think what I want is the BA25G, the Bearing/Accessory shelf. Or, and this is a long shot, would anyone have a 25AG4 Flattop Top section you might let go cheap? That's the 8' flat top section of Rohn 25G. I've got a TB3 thrust bearing I want to use if possible. 73 de Lew W5LEW
