'65 Barracuda Interior moldings under rear window

I've owned 3 early Barracudas and have never seen a plastic cover over the rear vents. It's always been body color. I've had a 64 and 2 65 cars in the past and none of them had that plastic cover. Don't know the production date of the 64 so I can't help in that way.
Thanks Keith, I've thought all these years there wasn't a cover, but its in the shop now getting ready for paint and my painter had another customer look at my car and said his had holes with screens saying it was a cover and the vent bar metal should be body color, not interior color. I'm going with interior color (Black) and that's all I need to do. The body is gold.
