I always find it best to just go down to the local DMV and ask them, preferrably before you invest a bunch of time/money. Even in the same state, the interpretation of the rules change from one DMV to the next. In Texas we always went to one town and not another because they used a different, and much simpler, way to do it.
I know you have the history on the car and this is a sidebar but many people have waited until the car was built and then had problems. I have even heard of a previous owner coming with a slideback and taking a car that he held the legal title to. Not what you want to see happen to a build that took 4 years and $30,000.
