Very Squeeky!It looks like there sheet metal bending alignment jig is off. Rear cornets have tons of gap but front upper corners overlap causing a annoying squeegeeing sound. Made two attempts to get a better replacement but all were the same. Ended up loosening the upper lip screws, bending the sheet metal out and applying strips of duct take as a insulator and extra sheet metal screws. All quiet now.
