Ahhh, the black/red D90 car. Early cars got a white D90 like the HP Cars '69.
When it comes to Camaro discussions of this nature I no longer trust what people remember. Dealers messed with cars in those days and one of the best examples is the #55 ZL-1 that was just sold. The selling dealer added stripes and 427 emblems; all still there with the original paint. Back in '70 340 Challengers and 'cudas were hot and hard to get so the ugly green Challenger a friend had as a demo got repainted black-when new. Vinyl tops were dyed or removed; wheels/tires swapped, whatever it took to sell them was done.
