rear axle spring perch flip

hey guys i have a 1970 dart that i have installed mopar ss springs in the rear i was hoping the car would sit higher in the rear the rear tire still sits in the wheel well i was hoping that the top of tire would be leve with wheel well arch. now i was looking and wondering if anyone had moved the spring perch on the rear axel so that the spring sits on top of the axle instead of the bottom. i dont want to put air shocks in or add a add a leaf dont want the car to ride harder let me know what u guys think and if u got pics of cars with this done let me know thanks much
