does ur car have airshocks in the rear were u can put air in them too lift it that was the thing too do on those older cars or im sure they make a kit its just a 1inch slab of steele that goes between the axel n springs dont take my word for it
Since the rear sits above the leaf springs, a block of steel will lower the reaend. I agree a HD 5 or 6 leaf set of new springs is the way to go. A cheap fix is to add a leaf to your existing set off of another set of rear leafs, I've done that in the past and works great.
