i have a 1986 t/a that i bought that never had the radiator lower air deflector it mounts between the radiator cross mounts and lower part of the front bumper. all mine had was the side rubber on the radiator. i went to the junkyard and got the pieces its actually 2 but becomes one once it is installed i forgot how it mounts it was of a '88 model t/a if any body can check how its mounted or if requires some sort of screw clips i know some of those need the plastic like buttons that have curved ribs on it. i will post pics on it to give you an idea of what i mean or if you know post some pics for me so i can reference them and install it on mine
