So here are 4 of the different coloured cowlings I have in this particular shape. According to the high arch manual I have, it shows this shape cowl has 5 colours: Green, White, Black, Orange and Yellow. I can't remember off the top of my head but the manual may also have a Corvette under this shape too. I could be mistaken tho.
Here I have the Green, White, Black and Orange.
Take note the black one isn't a store brand, well it isn't reported as one in the part's reference guide. It's the Commodore high arch cowling. But it's the same shape and style as the others.
