I love the idea of a Fays2 watts... i am not sure what the right rear suspension setup is though.. i think you will need some kind of over or under rider tractionbars... (Im getting a fays 2 watts through SC&C that marcus had developed for g-bodys... he is a fays2 dealer so give him a call)
if it were me building sosthing like that on a budget i would put in some stiff leaf bushings (aluminum perhaps), some stiff shackles or rear sliders.. and make some under rider traction bars possibly out of some top-bars from a tractor (cheapest way to get adjustable rod-ends in a decent size) somthing like this:
its a poor mans 4 link that uses the front part of the leaf as the top link
