1978-1988 Monte Carlo Radiator Support Air Deflector
This is the plastic part that mounts to your lower radiator support. This is an over looked item but it does have a function. It forces cool air up into your radiator. They are commonly broken off or damaged over the years due to curbs at parking lots & usual road debris. Whether missing or restoring, this is a great reasonably priced item.
