Well they are 14 yrs old and have sagged 1''. There're just tired and worn out. However (and you may know this), ride comfort comes from the shock and tire; the spring just supports the weight of the vehicle to allow the axles to "float" if you will. If I were you I would not put used stock springs on. If you like the ride height, a set of new OEM springs are fairly inexpensive @ ~130.00 . I would also replace the shocks with a set of Rancho's which on sale are ~150.00. I mean the labor is the same to put new stuff on as it is to put on old.
