This retrofit column is designed to fit your Camaro or Firebird and does NOT require modification to your original vehicle to install. Simply remove your old column, saving your original under dash mount and floor mount. Using an ididit installation kit, install your new steering column in place of the old. Using an adaptor, add an aftermarket wheel and the gripping surface of the new wheel will be in the same location as the original. Each column comes complete with a wiring harness adaptor.
