My brother Bernie came over to help again. First we completed the door installation on the map box and then switched to further preparation of the firewall. First we drilled the holes for the brake fluid reservoir, followed by the holes for the control cables for the throttle, mixture and propeller. A fourth hole was also drilled for insertion of the nose gear leg attach bolt. Then we drilled a hole in a firewall angle for the cabin heat control cable.To finish up we drilled the bolt holes for the engine mount and did a trial fit of the mount.
