The original rag joint may be used as long as it's in good working condition, but it is recommended that you purchase a new one. Using an ididit installation kit, install your new steering column in place of the old. Using an adaptor, add an aftermarket wheel or use your original steering wheel with the help of the ididit 1963-66 Corvette Steering Wheel Adaptor.
