I recently purchased a 71 GMC with a leaf sprung rear axle. The previous owner decided to warp them with a torch trying to lower it, so i need to get some new ones (obviously). My question is, do any other years of gm trucks have the same leaf springs? Im considering doing a coil spring swap at some point, so i dont really want to drop 400-450 on a set of new ones.
