Well on my drums they sure did not follow the Chrysler Diagram of applying paint. The is red paint on my front drums is all over were the wheel would connect. I know why they would not paint were the matting surfaces come together so the rim would sit flush and would be in balance just like when you do your brakes or change your wheels you sand the rotor or drum and the back side of were the rim attaches to create a nice matting surface. Red looks nice with some rims but not on some colors of cars. But I would love to know the reason why Chrysler picked RED and not another color. On my drums even the cap has red on it. My June Built 1971 Challenger is a very low mile drag car and I have owned it since the 70s and I was the one that painted black over the Red. Never liked the red showing through the aftermarket light rims I ended up running.
