Then shift the other part of the metal assembly until the third flat-head screw lines up with its hole. Check that all three screws are vertical and not tilted. (The shorter screw may not be long enough to reach the hole in the T-Plate, so just peer down the hole and look for the screw.) | Line up the two holes in the loose half of the metal assembly with the two longer flat-head screws at one end of the bed, and pass the screws through the holes.
