Part name?
 

What is the custom part that goes between the top of the radiator core support and the front cowl? The hood latch is open, and it usually bolts to the two hood pin supports on either end. I can't for the life of me remember what this item is called?

Thanks for the help in advance,

A closeout panel?

Yes, that is it exactly. Thank you.

I purchased a lower closeout panel, and the upper as well.

Do you know if these panels will allow/help the car to be more stable at speeds in excess of 140 MPH?

Thanks,

--Roger
