Best to check with the DMV, as to what the procedure in Florida is....seems that every state or province is different when it comes to this stuff.

Probably will at least need a sworn statement of sale.

If you can't find proof of the model year somewhere on it, they may want you to register it as a 2004, which means emmission testing and safety standards.

Perhaps someone can sell you a serial tag and ownership, or buy a parts truck with an ownership.
