Oh the old broken lower suspension pickup problem. I had exactly the same happen on my old Phoenix.
Firstly the rear lower wishbone pick up. To fix get it welded back together and some additional tragulation bracing (i went vertically from the pickup point to horizontal bar. Then have a 3/4" ID tube with a threaded insert welded in at each end and an M12 fem rose joint. This bar may need a bend in it to clear the tank. By using longer suspension bolts this bar can then link the O/S and nearside pickups.
Secondly the front lower wishbone pickup. With the rear fixed the front becomes the weak point as I found out). This happened on a trackday and KCW recovered the car welded up the break and strengthened by welding in some large gussets. You may as well have this done while the rest is being fixed,
Once these repairs and mods were done never had any problems and neither has Lee C. Just a shame these fixes werent done in the factory.
I would give ProComp a call (they are used to fixing Furys with similar problems)
