s.s. springs have more leaves to the front on the pass side, more to the back on the drivers side.
We ran 002/003 springs on a 3600 pound hemi belvedere, w/o a pinion snubber, every time we put one on it , it tore the snubber up. Ran just as fast w/o it. A whole bunch of spring movement because of too heavy a car, but it worked good for the sorry track surface, but way not close to perfect, the tires back then sucked compared to todays tires.
Back then, Chrysler always said, if u couldn`t match ur car weight w/ the right weight s/s springs, got to the next liter set. jfyi
