How hard could it be to fab up a 4-link for the front? I'm sure someone with an accurate understanding of suspensions and how they work could engineer and great 4-link to provide a smoother ride. A 4 link with a panhard bar would even be ideal because you would have more articulation. Now I don't know a whole lot about suspensions but I plan to learn a lot in the very near future. Don't the dodges have 4 Links on them?
I am getting some great ideas from this site. I believe it may be possible to use a Dodge axle from the information that I have read in this post.
