Wanted: Mopar A Body Super Stock Springs
Note for op:
If you want a PROPER set of ss springs, they will be biased so that the stiffer spring is on the passenger side. It will sit (slightly!) crooked with the right springs.
If you just wanna raise the rear, and don't necessarily want a pair of springs that WORK..... get two lefts or two rights. (Six full leaves would be the drivers side version.)
