One of the simpler jobs complicated only by the fact that you have to disassemble things to get to it. In this case, I needed to remove the torque transfer arms (visible as the brighter white in the photos) in order to finish drilling them for the bolts. Got them out, drilled everything, put them back in, installed the new Torque Tubes. Not bad at all. It gave me a pleasant morning in a chill, but workable garage to just be one with the building process.
