Strange inward deformation?, My 1974 914-4 has a strange anomaly Options

[Jezibel]

My 1974 914-4 has a strange anomaly that I cannot figure the cause of. [See attached 4 images of the left rear lower side panel.]

When I first got the car it had this unusual inward turn to it, assuming it had been somehow bent inwards a slight bit, so I manually pulled it back into normal conformation again.

However, in the course of driving the car's once--week 10 mile course (that includes a fast sweeping right turn freeway onramp) and returning to the garage, that panel seems to always want to resume that weird inward turn-in on that lower right rear panel (just in front of the wheel arch...between the left-side jack point and the wheel arch).

I haven't the slight idea what is causing this. The car has been "restored' and repainted a few years back, with any and all rust issues (if any) carefully addressed and rectified, but I am drawing a blank to explain this particular panel 'glitch.'

As usual, any and all insights and inputs on what may be behind this would be greatly appreciated. Thanks!

Pull the rocker and take pics. Unless you have pics of the restoration, anything could have been done to that area. Structure could be failing, etc. there is a problem but it will need some more digging to see what it is.

Also, take some pics at belt level, looking at the back of the car
