They were painted on, one wide, 5/16" two narrow, 3/16" I think. not decals. Someone with a steady hand for sure. I left them off my 300, I think they add to much clutter.
I just purchased a 69 300 and the original owner ordered the car with the stripe delete. I see the edge of what looks like a Rally wheel in the picture of the white car. Did they offer any wheels other than the 300 full wheel cover for the 300 in 69?
