need new leaf springs
I got +1" Espo springs and bilsteins. In hind sight I should have gotten stock height, but I always figured I could put on a lowering kit if I didn't like the rake.
My rear end was uneven height as well, but was still even after the new springs. So keep in mind this could be a function of your torsion bar adjusters being uneven as well. Mine were that has an effect on the rear.
