The last major structure piece to finish was to drill the holes in the new panel for the little subpanel that holds the control cables. At first i thought I would have to undue the cables to move this little piece further aft, but no. It fit okay. Just drilled two holes in the bottom lip of the Advance Systems Panel and they screw into the platenuts I had put in the cable piece.
So now the physical needs to install the panel are met. Next is to locate all the little pieces.
I also see that I've got the wrong Knobs and Auto pilot module. The knobs are suppose to be vertical and next to the EFIS. The Autopilot unit is suppose to be below the Garmin. I'll got those swapped.
