The engine bay is as close as Bell could make it to how it appeared back in 1978, the two most obvious exceptions being the modern battery and the horns along the right inner fender that play "Dixie." During 1978 this General didn't have those horns, but fans expect any General Lee to play the tune today.
I love how they restored this car. First repainted the original gold, then shot sloppily with the orange. Underhood returned to how it appeared during filming.
