The '64-72 Chevelle/El Camino/GTO retrofit column is designed to fit your Chevelle, El Camino or GTO 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 adaptor, add an aftermarket wheel and the gripping surface of the new wheel will be in the same location as the original.
Please note: the 1969-72 column does not have the provision needed for the OEM Neutral Safety Switch or indicator. An alternate method must be used.
