I registered my 54 1/2 ton in Florida with nothing more than a bill of sale and proof of insurance. I was asked if there was a current registration or tag....explained, to the best of my knowledge, that it had not been registered or tagged in the past 20 years. Signed an affidavit to that effect, paid the tax and registration fees and immediately received my new Florida antique tag and the title in less than a week. There was no inspection or even picture required.
Just a suggestion...I would present a well written, notarized bill of sale which included the number off the door post as the vin# and other pertinent info. Hope this helps you get your truck on the road!
