Haveing a hard time finding complete kit to replace leaf spring bushings and shackles for my 72 . Are 67 thru 69 camaro mono springs and bushings the same as 72 stock mono springs and bushings . I ask this question because a 69 camaro rear diff. is a direct bolt in and the front sub frame also and the camaro vendors have complete kits for the rear suspension but will not swear they are correct. Anyone else have this problem and did you come up with a solution.
