the last set of MP springs i bought were for my resto '72 Challenger. when i bolted them on, the right side sat 2" lower than the left. the MP springs that are out now are garbage. I wouldn't trust them. if you want springs, i'd go with Espo's Springs and Things. got 2 sets from them and they were great. just tell them what your doing and what you want, they'll make them up for you.
