Thanks 360 Cuda, i'm familiar with the rectangular pieces that came on the grille of the AAR and gran coupe, and I've seen cars with the 3 piece trim that goes on the rear quarter, and the 4 piece trim that goes around the tail panel, but whats with the "boomerang".
Also the 4 pc tail panel trim came on a lot of 70 'cudas didn't it? It wasn't specific to AAR I dont' think.
