If you look close at the orange Duster you can see where the corner of the quarter was drilled top and bottom and the holes were welded back in. I drilled the corner of two short pieces of angle iron. I put it behind the end of the quarter. I then put an eye bolt through the quarter and pulled the angle. This Duster was worse then yours. The trunk lid was out past the tail panel almost 1-2 inches. That is the original tail panel and the quarters . My brown Duster was hit the same way on one side like yours. When they are bent like the last pictures there is no hope. A little more than the " 3mm. tolerance would allow. LOL
