So many brackets and adapters. Why not just weld the "rare" sway bar mount onto your LCA? Ill make a pattern of a "rare" 65 "S" bracket and post here. Should not be hard to cut, bend and weld a piece of xx guage sheet metal. Rear bars have me looking, my "S" didnt come with one but I did see a 2bbl 65 273 Valiant at a show with a "factory" one under it. Dont know what thats about. The owner made a big deal about it too, ie, "you ever seen one of these???" I heard Camaro rear sway bars work if you "adapt" them.
