Tank mount goes behind the tube. It should also be glued to the wingtube sleeve for additional stiffness.

Vector rods need to be trimmed slightly. Degrease the threaded rods very well, then hysol them into the carbon tubes with an adhesive you really trust. If those pullout it's game over.

Carbon rods over the threaded rod just free float. They're provided to increase the stiffness of the threaded rods, so they can't buckle under extreme loads. Most critical for the flaps. There is a manual that is mostly pictures that you can get through your rep.
