Rocker Panel alignment. Is this original?

[GIZZ]

I'm 90% sure the rockers on my '69 panel have never been replaced. The fitment at the rear of the rockers panels does not look great to me, both sides are the same. The front alignment and alignment to the door are great. Its just the rear of the rocker, is this how it was? Was is bottomed out?

The other half of it, with the rust pitting, should I just repair it? Or replace a part of the rocker(saw this on YouTube), or the whole rocker. I think I have pickup rockers, not sure if there is a difference.

Here is what I'm talking about,
