Ford Shop Manual calls out body heights quite specifically, for 2nd. gens. I suspect this is due to the greatly amplified amount of affect due to slight torsion bar variations. 3rd. gens seem always to be pretty even-keeled, level. Every front suspension scheme has it's ups and downs, I personally dislike MacPhersons, and even torsion bar springing. Chrysler used them possibly as a sales gimmick, (different, thus better), back in the '60s. Abandoned them. Leaf springs suck, "wind-up" under applied torque, don't lend themselves to front at all, (forget Jeep and Scout), and can allow side-sway. Good, independent suspension using coil springs and side-sway movement are tops for me. imp
