Not really an answer.......but Herb Adams......who was a Pontiac engineer responsible for a lot of good things on the 70 TA....recommended replacing WS6 front coils with base bird springs....after removing a 1/2 coil...

This lowered the car by an inch....while increasing spring rate.

The big sway bars reduced the need for stiffer springs
