Does 69 have different headrests??

I have a 68 Dart GT with the headrests that have the chrome band around them. I just picked up a 70 Dart with the same headrests. I'm parting a 69 Dart and it has very different ones. No chrome band and a lot thicker. Are these 69 specific or model specific or did they change to the different ones in 69 and my 70 just has the wrong ones?
