How do I get a title for a manufactured utility trailer in NC w/o an Official bill of sale or title to trans? - how do i register a utility trailer

I bought a utility trailer w / or as a pair of SC (they moved here in North Carolina a year ago) Orig owner no longer include the sale of long ago, and he never registered because the labels and titles are not on trailers that are required in SC. I do not know what to do. DMV was not very helpful.
