1978 Volare roadrunner... option list for hood scoops?

Was just one hood scoop (if any) listed as an option for a 78 roadrunner? We just bought a 78 RR, and the six pack hood on it does not fit real well to the contour, yet the owner says its OEM (its very glossy, makes me wonder). Also if someone knows a link to one that is correct, that would be great....
