also if you don't have it in the park position you will not be able to remove the ing. key If you have the factory shifter still, Shift works as different kits to make the factory shifter work with out the driveback linkage and still have backup lights and netural safety switch, you just need to tie up the arm on the lower colunm so it stays in the park position. They also have a kit to adapt the factory shifter for use with the overdrive trans. I have headers so I can't use the driveback linkage, so I installed the NS and BU switch relocation kit, it works great
