One or two words of caution on these. I would routinely check the well-nut bolts to make sure they are snug. If you decide to use threadlock on them, make sure it is the removable type (not the red loctite). I now use elmers tite-n-up, or a small dap of blue rtv silicone on mine after I noticed that one started to creep loose a little bit (culprit turned out to be a slightly warped spinner causing vibration). The blue RTV will allow you to remove the mount without spinning the well nuts, or tearing them trying to grip them. The red loctite will cause the brass insert in the well nut to come out of the well nut, or spin around inside it.
