I started doing some fine tuning today but didn't get very far. I had some other work to do but I managed to get the peaks of both halves to align and started smoothing out the rear panel. I still need to work the stress out of this rear half before I weld the two together. If I were to weld them as they are, the tension from the rear panel would transfer to the front half and cause even bigger problems.
I still feel that most of the problem comes from the dip in the peak ahead of the tail light opening. I think I'll try some heat as George suggested. That might momentarily allow the metal in that area to relax. If it does, the metal will move to a point where there is no longer enough pressure or tension to make it go any further. I'll probably need to do another shaping session in this corner but I have to find out what caused this for two reasons; first, I need to know what happened in order to repair it. Second, I have to make another one for the right side. I'd like to avoid going through this again so I need to know what caused the problem.
