What has been replaced on it already? You doing all the work yourself? How many miles on it currently? If doing all the work then I'd suggest new Dorman front lower control arms, front sway bar, struts/springs/mounts at all 4 corners, valve cover gaskets/grommets, LIM gaskets, engine and trans mounts. Once you get a solid base then you can mod it. No sense in trying to mod something that has a bunch of broken/worn out parts on it already.
