It was a thing, it was the Ghia with a ralleye steering wheel and black grille instead of silver. I have a Ghia Sport grille in ElSuperPinto. https://en.wikipedia.org/wiki/Ford_Mustang_(second_generation) (see 1977)I don't know that the 'Sport Package' was anything other than a dealer installed thing. I don't see any VIN# designation for it.
Could you send some pictures ? I was thinking of doing something similar to mineWow that how my bumpers looked.
I still was able to use the core to hang fiberglass smoothies on it and have some protection.
