1989 chevy caprice ls brougham steering column

I have a 89 Chevy caprice Ls brougham Im lookin for a steering column. A guy selling one listed 88-94 Chevy GMC Truck Tilt  STEERING COLUMN For Automatic Transmission. It looks exactly the same but the floor plate is different, will that matter? Or can some help me out with other steering column that’s compatible with my car? I also need the length if that’s possible. Thanks
