Drivers side fender contour is flat?

I noticed sense I restored my cutlass that the front driver fender has a noticable flat spot in the front contour when looking down the side of the car. I thought it was just a dent in my fender or that when I attached the core support it caused it to distort. I was at a car show last week and saw another 64 and it had the same distortion and it was a white car even. You guys ever notice this on your 64? Is it common?
Thanks
