We have a miscommunication. Ford does not, will not give a rats a** how good a job you did. Their point will be that you did not install the correct replacement parts. IE: The inserts used on the PIU or, the XLT with the roof rail delete box checked off. If you never have an issue, you're gold. If it fails, you are up the creek. This is a darn near $60k vehicle. Why jury rig it ?
