Second Generation Camaro Inner Fender Paint Color

[Andy]

Can any of you tell me what the correct shade of black is for the inner fenders on a later second generation Camaro? Specifically 1978? I had to pull the passenger side inner fender out of my uncle's Z/28 to replace a blower motor and it has some white overspray on it from when the car was repainted 30+ years ago. I'd like to sand it down and repaint it the correct color since the car retains the stock appearance. I will pull the drivers side and redo it to match once I wrap up a few other things on the car.
