1967-1968-1969 Barracuda Rear Trim?

68 is the only year that these cars left the factory dang near without brake lights.
In between on the trunk lid was body color. Ma mopar did offer a reflective tape to place there if ordered. I see that as a bandaid on their feckup. For 69 they went back to the 67 design but with styling differences.
The only drivers who really appreciated these yearly differences were the police. Their headlights were no better than anyone elses. License plates weren't as reflective as todays either. Officers are expected to familiarize themselves with the annual changes so they can properly identify the vehicle ahead of them.
