My ignition and door locks take different keys. I am assuming the ignition was changed at some time by a PO as the original key fits the door locks. I would like to rekey the ignition if possible. It is one of the projects in the "101 Projects for your 911" so i am assuming it is possible. I have a '70 911T. The project in the book describes a key kit which consists of 25 tumbler pins. Is this doable and where do I locate a key kit if it is. Many thanks.
