I HAD LOST SOME OF THE GARMIN BACK TRAY SCREWS IN THE PROCESS OF BUILDING SO REMOVED THE AVIONICS AND INSTALLED THEM. THESE ARE 3/8" LONG SS 4X40 NON MAGNETIC SCREWS THAT I GOT FROM ACE HARDWARE ALSO FOUND ANOTHER USE FOR FUEL LUBE JUST STUCK SOME ON THE END OF MY LONG NECK PHILLIPS SCREW DRIVER AND THE HEAD OF THE SMALL SCREWS AND PUT THEM IN, WORKED GREAT
