FWIW
Geogia and Alabama will also work. Both now have title laws but on older vehicles, only a tag receipt was/is required for transfering to a new owner.
In both cases, you get someone you trust to buy a new Tag, hang on to the tag receipt for 6 months and sign it over to you.
Done this many times on stuff I KNEW was legal but papers were lost. (Of course, you can "post date" the transfer on the tag receipt - but, you can't turn it in prior to that date.)
