OE Springs often Won't cause this problem. Aftermarket springs can and often will.
Replacement struts could wrong part even if box/catalog say is right.
Control Arm bushings maybe bad. But that bad to see very easy is likely to cause other suspension problems.
84-87 Cradle and it's bushings could be bad.
These may not cause other problems except under a set of conditions. Example: Turn normal maybe fine and have problems turning hard left, right or both.
Having crap in the cabin or trunk can make car sitting low. Worse for crap in trunk because that weight is Behind the rear axle.
Could be rear isn't low but front is too high. Or rear a bit low and front a bit high. Either is possible when shocks and struts are not same brand and type. Using non-gas units on one axle and gas unit on the other is known to cause problems. Mixing brands/types can to same.
Engine/trans swaps may cause same if either or both are heavier then OE setup.
Check on very flat very level concrete surface w/ good measuring tools to various parts of car's frame.
If front/rear tires are Not = sizes then must shim the tires so axle centers are same distance to "ground."
Shim tires by driving on metal or wood.
You could jack to shim the tires but need to drive off and on to "reset" the suspension before measuring the frame. (Driving just 1 - 2 yards should cancel jack winding up the tires and car.)
