I am sure there is a simpler method of doing the bracket but this design allows me to run cables, wires etc. from firewall forward back to either instrument panel. Image three shows a fairlead for the fuel shutoff lever that ends up back in the rear cockpit. The valve will be controlled by a long piece of tubing with an L-shaped handle bent on one end. The other end will be reamed, drill and cottered into the fuel shutoff shaft.
