I can confirm the part number is CZK3882 for a 94 NAS. I ordered these from the dealer in 2004 and never had them cut since it was kind of pointless to lock the doors on a soft top anyway. I recently added a hard top so locking the doors is more of a priority now. I called the dealer about a week ago and they were not much help getting the keys made but they recommend a locksmith that they out source that work to on the older trucks.
