Quarter panel curve?

[do it again]

O.K.,on a 71 to74 Javelin ,in the rear quarter section, behind the rear wheel,below the crease ,is the curve supposed to flow all the way to the bottom or is it supposed to have a slight flat spot?The reason I ask is I ordered a patch panel for my toy and it has this flat spot about half way down the curve.It doesn't look like a dent it looks like it is supposed to be there! I can't look at the other side to confirm it also had repair at some time in the past.Just thought someone else ran across this at some time.
Yeah I know,quit laughing,thanks :p
