Road Runner Nest

What color were the vehicle emission decals on a 1971 roadrunner 383 auto, green or blue? I took mine off during the restoration and the picture I have the label looks to be green. However, the one that I bought from ECS is Blue # 3614873.

thanks

In my experience, originals were blue. Photo is from a survivor.

I used to recommend Performance Car Graphics for the small decals BUT since ECS came along there's no comparison. ECS makes the most accurate small decals.
For comparison, ECS on the left PCG on the right.

Thanks Eric, will be going with the blue!!!!!
