I switched to the 002/003with a 1/2 leaf on the passenger side, from the beefy SS springs in my Charger, havent test yet but from advice from Chuck Lofgren he said for a starting point passenger side one clamp right at the 1-2 leaf next to the hanger and one on the 2-3 leaf,driver side one clamp 1-2 leaf next to the shackle and a clamp on the 2-3, also about a 2-3 degree rake, level the car with the TB which will pre load the right rear because of the 1/2 leaf, 7 degrees pinion angle and a proper front end alignment
