okay first of all what is so bad about the saggy butt look? it looks better than having the rear higher. and i have 4" of suspension right now with the stock driveshafts, if i go with some zero rates on the front will i need a new driveshaft? and concerning the shaft, mudbogAD told me there was a spacer out there to "lenghten" your front shaft, is there? and where can i get one?
