I have the new lowering hangers on my 73 chally road race project. I love these hangers they are very high quality and built much stouter than the originals with better studs already mounted in place. If you are going to lower your cuda/chally don't flip! buy these instead!! I have tried to flip my originals and I ran into problems because the holes for the studs are closer together at the top than at the bottom so it couldn't work without fairly extensive mods.
