I often thought of this when looking at 67 Belvedere GtX's on Carsonline. look at 10 cars and notice the fender lip height on the rear are at different levels on some. SS springs maybe?
Yeah but how many of them are actually at the factory ride height spec? Most modern alignment shops do not have a good understanding of how you can change the ride height with a torsion bar adjustment. And just looking at cars online you have no idea if the car has been intentionally lowered, or is just running around on worn out factory suspension and hasn't had an alignment in decades.
