This retrofit column is designed to fit your Impala or El Camino 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. Add an aftermarket wheel and the gripping surface of your new wheel will be in the same location as the original. Comes standard with 8-position tilt, self-canceling turn signals, 4-way flashers, knobs and levers, 3 7/8" wiring plug and a 3/4" 36 lower shaft.
