Hud number

I own a 1980 new moon mobile home. I need the Hud number for the home. I have remodeled and there is nothing left of the old trailer except the frame under the original side of the home. The tongue was cut off and brick underpinning was added. All walls and cabinets have been replaced. There is nothing left of the original mobile unit. I need the Hud number or compliance certificate because I want to refinance and according to the Lawyer I can't close without this information.Please help, I need the money for a new roof.
