Hello Allan,
I have a thought that may work out for you. I have an O-320 powered Long that I had to take the wings and engine off due to hangar space issues (and a large family). What makes my Long a possible answer for you was that it was made in Canada. It was given an N-number years ago, but all of the approvals and inspections that Canada requires was completed.
Just a thought. I haven't put it up for sale yet, but may soon. I would sell it as a project due to its current assembly - but it's a fast plane and you could put in a new panel if you were so inclined.
Doug
