I know some years they know percentages of color, but not exact production... anyone have any info on 72 cuda/barracudas?

I have a black 72 340 barracuda and after some research I saw it's one of 490 made. However fender tag is lone gone... already cloning into a 70 aar, but still curious to how rare it really is.
