Springs to raise rear on 72 malibu

[bafflefinder]

THanks for the info. I am still looking and now am thinking about station wagon springs. I just bought this car and am going through the from end, control arms etc.and also the rear tires would rub on a dip. Also the drovers side sits slightly lower than the pass side. I ordered heavy duty springs from NPD and they are 12.5" tall, unloaded. The old ones are 14.5" tall so now my dilemma is are the old ones wore out. I need to find specs on the springs and figure out what I have. If anybody has any old springs that they know are stock and can measure them I would appreciate it.
