Grille Frame to Radiator Cover?

[RamZCharger]

Has anyone come across under hood dress-up panels that attach to the grille frame and extends towards the radiator, basically covering the gap north of the radiator?  I am not sure what you call them, but have seen them on other makes but not for our cars.  Either a brushed or polished metal or even painted, I have attached an example for a Camaro.  I'm specifically interested in one for a 68 Charger.  Any suggestions of where to find is very appreciated.

I have never seen a mass produced piece anywhere. I think you will have to do-it-yourself.
