This retrofit column is designed to fit your Nova and does NOT require modification to your original vehicle to install. The 1967 Nova's can reuse the original under dash mounts, but it is recommended that you purchase a NEW 1962-67 Nova Floor Mount. Using an ididit installation kit, install your new steering column in place of the old. These columns come complete with a neutral safety switch(shift indicator not included). The shift pattern on the column allows you to use either a 3 or 4-speed automatic transmission. A shift linkage(new or original)is required for installation and will attach to the lower shift arm provided on the column. Using an adaptor, add an aftermarket wheel and the gripping surface of the new wheel will be in the same location as the original.
