1973 340 air cleaner color

Blue engine, orange air cleaner is correct for 73 340. 72 and some 73 had the flapper in the air cleaner base. Most 73 no flapper.
I dont know what they called the color but it was close to street hemi orange but not quite. A little brighter.
I have a couple unmolested ones here if you need to see the color. The 400 one pictured above tells the story. Same color.
