BEST ANSWER: I am not seeing anywhere that these part numbers are connected. Our parts are designed to be exact replacements for what came with the vehicle, so as long as your year, make, model, and specifications match up with our listing, these will definitely fit and function just like the original. Please let us know if you have any other questions.
