Greg,
Yes, the picture I posted shows that the "attachment point arm" that the rudder cables and the springs anchoring them to the firewall ARE part of the reinforcing kit plates. This is the part that appears to have broken in your pictures, so it is addressed by this kit. (Obviously, there is NO internal tubing added at this point, like there is to the torque tubes.) The factory reinforcing plates are molded to fit the curve of the tubes; are stout pieces of steel, and should be a proper strength addition.
