I am trying to decide whether to replace the worn bushings on my control arms (front and rear) with Energy Suspension polyurethane or buy new arms. Pickings are slim and expensive for my year Impala. The car will be a "spirited" daily driver which is why I am looking at suspension upgrades. I was told that the 77-79 arms are compatible with the 72. Is that a true statement? If so, I can just hit up Rock Auto and use MOOG replacements. If not, Spohn makes upper and lower arms, with zirc fittings, for the rear at a decent price (nothing tubular for the front). Global West is too much for my budget. Are there any other products or compatibility options I can use?
