After changing these big ol 14 leaf springs I'd welcome a set of Camaro's! Be careful. They are DEAD WEIGHT. If you are under there and they decide to slide, you may not be able to control them and they could land on your head or mash your hand. Otherwise, very low tech and straightforward r&r. Definately what Jerry said about friction pads of some kind. At the very least, they take out one source of squeeks and probably make for a smoother ride.
