What's the problem with this 1967 Barracuda trunk trim???

Because it sits out slightly further compared to 67. 67 sits in the "concave" part of trunk lid. If that makes sense. Shut the trunk with something hanging out, the bottom piece on 68 takes the brunt. Top piece if someone pushes down hard they might damage it.
Hey HemiSSDart, what is the reason for the 68 sustaining more damage than a 67?
