glove box cover

In putting my glove box back together i notice their should be two small bracket's with rubber bumper's in the upper corner's of the inner frame of the compartment to keep the cover from rattling and a sleeve for the open button to catch to keep the cover snug when closed?! their is a slot in the glove box cardboard box so the screw for the sleeve slide by! I'm missing the sleeve and the bracket for the left side??
