I have a defective Series 2 carbon fiber Gitzo tripod that Manfrotto replaced for me because it is no longer made and they couldn't replace the defective leg. They returned the defective tripod so I'm trying to make it functional. The problem is (for those of you who have cleaned or taken apart your tripod, you will know what I am talking about) the little white plastic bushing doesn't seat correctly so it slips off and gets jammed down into the top end of the leg (it is possible to fish it out). The problem is not the bushing, since I and they tried replacing them; it is the leg. The result is that when opening the leg it comes all the way out and separates from the rest of the tripod. I'm wondering if there is some way to secure the bushing in place. Glue? If so, what type? Any other suggestions. Thanks!!
