I am about to start the bodywork on mine to. It has the same issue but I didn't notice it until your posting. I had noticed the center strip piece above the
oil cooler hole is bowed in about 1/4" and I was intending on fixing that. As has been said many times on CC these bodies were never perfect as the originals were hammered out by individuals and later splashed with glass to create molds. Don't start measuring or you will find a lot more. I think it's all about blending in. A friend has an LA Exotics that has a fender issue that bugs the heck out of him. I haven't seen that problem yet. I just want to find the big ones before it's painted. We all have to decide how far we want to go.
