AXVC,
"Ready for battle" is exactly the wrong attitude. You will want to be your most charming, friendly, positive, self while dealing with the DMV. You really need to develop a friend there who can help you keep that puppy on the road. I registered my car as a "Specialty Constructed Vehicle" first. Then went back under SB1578 (same as SB100 for already registered cars) to re-register as a 1965 Cobra. I would make an appointment and have a friendly talk about all the hoops and hurdles that are necessary to get through the process. And be happy about it! At least, until you get outside when you can scream and kick the building.....
