Is the A-Body torsion bar spring rate the same as B-body cars? What I mean is, even though an A-body uses the shorter bar, it also uses a slightly longer lower control arm. Does this in any way mean that a 1.14 T bar in both cars would mean approximately the same ride and spring rate?
I ask because I have 1.15 Bergman Auto Craft torsion bars in my 70 Charger and the car rides great. It is firm but feels solid and capable without feeling like an unloaded dump truck.
