Hello aviators,

I am starting a 777 home cockpit, and the first part I'm building is the overhead panel. Before I can buy the panels and electronics, which I have a potential deal lined up, I need to plan exactly how it's going to fit in my house. I need the overhead panel dimensions, and surprisingly I'm having trouble finding them. I'm not building the frame before getting the panels, but I need to know the size of the overhead before purchasing the panels. I'm expecting it to be somewhere in the 3x3 ft area,, but I'm not exactly sure. Thanks in advance for the help!
