New trunk seal, now I can't close the trunk

The seal I used at my 67 B'cuda trunk is the D on a U channel type. Came from a Ford truck door opening. Works very well.
Before this thread I didn't know of any A-body having other than the duck mouth / V type seal.
The final years of A-body, especially Dusters, were different in a lot of ways so I'm not surprised.
And that seal does look like it could be installed 2 different ways.
Subscribed to learn something. Good luck with it.
