This GM style retrofit column is designed to fit your Mustang! Some modification to the original gearbox and wiring will be required. This column features a GM upper shaft, and a 3 7/8" Wiring Plug. Comes complete with a female end plug for your wiring. To install, simply remove your old column, saving your original under dash mount and floor mount. Use an ididit installation kit to install your new steering column in place of the old. Using an adaptor, add an aftermarket steering wheel and the gripping surface of the new wheel will be in the same location as the original.
