Many owners dont realize that the leaf not only supports about 40% of the weight in the rear of a '64, but also acts as a sway bar. If the cars try's to roll to one side, it compresses the leaf which pivots at the center and pulls down the other side, helping keep the car level in a hard corner.
Many years ago I would often see pre-'64 Corvairs with the wrong shocks that allowed the rear suspension to drop way to far and increase the tendency to "tuck under" in a hard corner. If your EM suspension of any body type drops too far, or you just want it to drop less, you can place spacers between the lower shock mount and the swing arm.

FYI, The stiffer springs were just that, stiffer and didn't effect height so the mono-leaf spring is back on for proper ride level.

You started out right but came to the wrong conclusion. The leaf reduces roll stiffness in the rear which increases body roll. The front anti-sway bar does the opposite. It increases roll stiffness.
If you read the specs the '64 has slightly lower numbers on the skid pad.

You can attach here directly from your computer, but, you must make the file size under 500KB. Just use the attach button above the typing box and browse to the photo. I use a program called irfanview to reduce photo size but there are others.

Correct, the leaf in technical terms is a "de-stabilzer" it de-couples the rear axle pair roll rate. A high roll rate from stiffer rear springs or a stabilizer bar would only contribute to swing axle "jacking effect". No rear roll rate = no rear roll. Ryker Motorcycles is a good current example of this, no rear axle, no roll.

Here's a swing axle Kieft. No rear roll springing. A shock cord is used for the "de-stabilizer" spring.
