Worked on the dashboard today. Installed the air vents, CO detector, propeller controller, interphone and autopilot control panel. I'm glad I decided to install these components prior to dash installation because there was quite a lot of adjustments need to be done, which would have been very difficult if the dash was installed. i.e sanding the air vent holes, Interphone unit and the CO detector were touching the side edge of the dash, therefore trimming the dashboard was required. Installed black 4mm screws to attach panel to dashboard, much better than silver.
