I bought a 1972 K5 lifted (I am not sure how much), and the rear diff is pointed up at aprox a 45 degree angle (points to t-case). I read that this ok for a CV type, but for mine it has to be straight? How do you change / adjust this? Any help is really appreciated. -Mike 1972 K5 CST Blazer - 350V8 17x40x15 Made for Mud!
