If your 1963-1982 Non-Power Steering optioned Corvette tends to "wander" or has vague steering feel, you may need to rebuild the Steering Ball Stud And Cup. This kit includes reproduction ball stud, ball stud cup, rubber seal, seal clamp, clips and all other parts to complete your rebuild project. It's also a good idea to check other steering components at the same time you are installing this kit. Tie Rod ends, Pitman Arms and Idler Arms also may be worn and require replacement.
