I'm in process getting a 50 model updated in Virginia from titled by engine number to the cab/truck serial number.
They are aware that vehicles had been titled by engine number and at least in VA seem willing to make the correction after submitting a form, title in your name, money, and a lengthy wait (1.5 months and counting). Next someone will come to inspect the truck and relevant numbers. Finally I assume I'll get a fresh corrected title in the mail, but we haven't gotten that far to know for sure how it pans out.
If you end up doing something similar for NC find out for sure, and double check, then ask again where exactly you should send the paperwork. I sent it to the Virginia DMV, the PO box and all exactly as listed and instructed on the form. They still haven't seen/found that one going on two months later, apparently I should have addressed it to a particular department within DMV, they only tell me this after the fact.. While the first attempt churns its way through the various offices perhaps for 3 months or more (their guess).. I sent a second attempt as later instructed (already received and in process). Also get a signature confirmation when mailing it.
