Had the exact same problem you do. Sagging old 6cyl leafs in my Dart. Replaced 'em with 002/003 S/S springs from Mancini. Ride height was perfect (for me) after they went on. Went from wheel lip on qtr below the top of the tire, to wheel lip just above the top of the tire. Cranked my T-bars up a little to get the front up some and the rake is perfect! (again, for me) Some prefer a lower stance.
Passenger side sits a little higher than Driver side to account for twist when you launch but it doesnt bother me.
Before & After pics attached....sorry I dont have a good side shot of After.
