747-400 fmc case

Hi all, I have recently got a job working on sheet metal cnc machine tools, and as a project I am building the case for a 747-400 fmc, which one fine day I hope I will be able to use with ps1. I am a qualified electronics engineer, and I now have access to laser cutting machines and punch presses, as well as mild steel by the ton, what I dont have is the plans for the fmc case, or any dimensions for the keyboard layout. Any info would be much appreciated, and if any uk simmers want anything cut from steel between now and christmas I may be able to help! regards,anthony croshawp.s. please email me with any plans, at [email protected],cheers!p.p.s any help with the electronic design would be also appreciated, although I am more concerned with the case at the moment!
