Did some prep tasks; I'm going to use wire loom to protect the fuel lines, pitot-static, and wiring inside the forward vertical channels that help in routing these items thru the tunnel and up to the panel. 3/4" should fit just fine.
Riveted the reinforcements inside the torque tube tunnel. The reinforcement gives extra strength for the inner seat belt attachment (large unriveted hole in the pic below). Empty holes correspond to the seat pan and will be rivted from the inside once installed.
Removed the torque tube assembly to install tha rudder cable fairleads. Had to trim one side due to proximity of the fairlead to the lightening hole.
