I see pictures of a few Darts, remember that the wheel opening height on the Dart’s is lower than the Valiant the OP has. Getting the top of the tire even with the wheel opening on a Dart would take an insane rear ride height.
On a Valiant it’s more like a +1” spring or a set of Super Stocks like 69383valiant posted. It’s still a rake, but really it’s probably not much higher than toolmanmikes car.
