Depending on whether or not the DMV official you're dealing with has PMS on the day you ask a question, you MIGHT get good information about how to get a LEGAL ID number assigned to a vehicle you're restoring. Most states have a method of getting numbers assigned to restored or home built vehicles, but the necessary procedures and hassles vary from state to state, and sometimes from one county to another. Just pray that you don't encounter some incompetent jerk who thinks his/her Civil Service job is a license to be rude and uncooperative.
