This is a picture of removing the original LH quarter from my 1970 nova. There was no indication of previous damage or repair here. You can see some brass at the front lower corner from the front edge of the seam inwards towards the inner rocker. Nothing along the outer seam to speak of... maybe a little flowed back... mostly in the inside lower corner.
I also found similar brass in the top inner corner of the B pillar at the roof rail.
