Default Naca duct hood

Hi, I've seen hoods with the 2 ducts in the front of the hood. does anyone know where to get these? I'm assuming they must be fiberglass. Or is someone welding these in? I really want one for "Bertha" any help would be appreciated.

Thanks but those aren't the ones I'm talking about. they are mounted in the hood they are flat and point to the inakes. Those plastic ones are rough not worthy of a street car.

They offer the ducts here, at least in their paper catalog.

The only benefit is with those ducts facing the rear of the car, used as air escape. I live in Florida, and those make a huge difference on a 100 degree day in traffic, as heat is dissipated to the atmosphere and not trapped under the hood. I have them on one of the widebodies but was never able to locate them for fitting them onto other cars. They're kidney shaped. Not excatly NACA shape. I may have to make a mold off what I have one day...but have higher priorities for the moment.
