All of the vents on my 2011 f150 are broken I know I can get the replacement vent inserts , but does anyone know if I can get just the louver inserts once you take the cups out if you take the trim off all it is , is louver inserts that do the 360 degree turning . The 4 set is 240$ for oem but all I really need is the insert louvers. Thanks in advance if someone can help me
