I came very close to trying to get a roller sans engine/trans shipped through my wife's work as they import from south America often and her contacts down there agreed to help me. As it is it is darn near impossible to get it through without paying an importer a heavy price and if going undocumented like I was going to try was too risky as they xray the containers. I am still working on it and have an American in Guatemala looking to ship his car home so I may be able to get him to buy it and ship it as his, he has done it fairly hassle free in the past. As of now it is a long shot but I want one bad.
Yeah, there was a thread about it on Pirate a while back. Basically it all comes down to being a major PITA to get one imported. That said, its probably a lot easier to get a Canadian spec than anything else.
