      I can look it up, But from what I remember, it was for example the "El-cheapo" plain-jane lumina that had the lowest rear leaf spring rate (FE-1).
      Yours would have the FE-3 (stiffest) leaf spring and largest diameter control arm.

      Just look for a older w-body that lists the FE1 option on the part list identification tag in the trunk on the spare tire cover.
