My recent discovery of multiple rust problems with the trunk and rear frame rails has lead me to the conclusion that I not only need to minitub the 65 but also replace the frame rails. I am contemplating having some 2 by 3 rectangle tube mandrel bent to make new frame rails and then building a four link with coilovers (when I have the money, but it will be cheaper than completely rebuilding the stock suspension). I need to know what the advantages of a setup like this are. How does it hook up better than the leafs and shocks? If anyone has any suggestions, let me know, thanks
