The upper feeder house seal and the lower feeder house seal are both the same. Part number for seal is 71367416 and the retainer is part number is 71368295. There is a galvanized shield on two pivot pins that fills the gap below feeder house to the main frame. If you lift it up you will see the trans. There is another galvanized shield on a rod just below feeder house that is held up against rubber seal and retainer by two metal straps on bottom side of feeder house.Both shields are the same part number. As the feeder house pivots up and down the metal straps hold the galvanized shield tight against rubber seal. If floor is worn through, I agree looking in to floor mod. kit from Dan Hurrt.
