How to find a Dodge-Baracuda of early 70's model being an overseas participant?

There is no such thing as a Dodge-Baracuda. The Barracuda was made by Plymouth. Dodge made the Challenger which was their version of the Barracuda. In the early 70's both of these musclecars were designed to compete with the Ford Mustang and the Chevrolet Camaro. The 70-71 Challenger and 'Cuda' are highly desirable in todays collector car market, especially the hemi versions. Try googling collector car trader online.
