Dcal1963

So, I was looking at a 1969 Hemi Roadrunner picture and noticed the 2 small bumperettes on the front bumper. For some reason (I don't know why) I've never noticed them on there before. Then I thought maybe they are for the GTX....but I see pictures of both RR's and GTX's with them. Was this a late '69 addition? Were they optional? Just curious ...
