Prepped Center Subpanel

I finished installing all of the nutplates on the subpanel.  Here you can see a set of 4 K1000-06 nutplates on each side of the radio stack hole.  At the bottom, you can see some K1000-08 nutplates that support the control cables as they pass under the subpanel.

There’s an additional K1000-08 at the forward end of the center rib to support the parking brake cable as it arcs across the firewall.

Finally, I riveted the ribs and attach angles to the aft side of the center subpanel.  Other than priming, this is done.
