New leafs too high, how much will they settle?

P3412003 is the part number. What kind of springs do you have in your dart now. And when you say you want to lift it up a bit how much is a bit (1 inch, two inches)?
I have no idea. They aren't stock. They don't look all that old and have fewer leaves than any A body I ever worked on. They came with the car. The guy I bought it from thought they were some kind of lowering spring. The top edge of the wheel is up above the quarter lip. This is the lowest dart I have ever owned. Transmission crossmember is only a couple inches off of the ground.
