I also need a new set of springs for my '72 dart and not sure what height to get. the current old originals sag quite bad and have the rear end sitting very low so bad that i installed air shocks years ago to get the *** end up but i would like to do it right and get new leafs but not sure on weather to get +1 or +2" or what because i dont know where it would sit with fresh stock springs because these sag so much.. I want a slight stance to it with the rear being a little higher than the front but not too much..
