Your post said 4-link suspension. Are you looking to put on a 4-link ?
I used to build these a lot on Jeeps and early ( 60's ) Bronco's, because to the short wheel bases, for rock crawlers. They work awesome if done right, if not done right can down right kill you.
You are talking about a lot of custom fabrication for one of our trucks, since there really is not a market for it. Unlike when I was doing it, it was all trial and error at first. Now they have kits for Jeeps and such.
There is enough info on the web now you can read for months on the subject, and I suggest you do if you want to go that route.
Good luck and hope to see pics if you do a link system. There is also a 3-link that is not as complicated to do.
