Lightweight, new here but I did read though the whole thread. Shame so many of the pictures are gone.

But anywho something I noticed with the dented quarter panel thought.
When I first looked at the silver Dart photo, it to me looked more like a buckle.
Maybe from an over zealous pit crew member shoving on the quarter as the car kicked sideways doing a burn out. But then I started seeing other Darts with similar repair areas. Can't be that many ham handed crew members, so it had to be something else.

What nailed it for me was the silver Dart with the blue side side stripe. No one in their right mind would paint over that big of a dent. And the dent in front of the bumper rang a bell with me.

If a Dart launched hard, twisting to the right, the right rear bumper would hit.
In doing so denting the quarter in front of it. It would also tweak the rt rail. Maybe enough to buckle the quarter. And if the car only had a 3 point roll bar, it wouldn't take a lot to do so.

To add to it, I found some shots of a Dart that got hit on the LEFT rear.
The right quarter, along with other damage, has the signature buckle above/behind the wheel house. If you look at the shot from the left side, you can see there is no support behind the wheel house on the right side. Confirmed by the third shot showing the quarter removed.

Thinking yours may not be all alone, but maybe one of a group that pulled one heck of a wheelie, smacking the rear bumper, and buckling the quarter.
