Interesting that you mention the 'Border Bandits'. My earlier post, reply #17, shows my brother's pair of 68 R code cars that were sold new at Sandy Elliott Motors in our home town of Chatham Ontario, home of the Border Bandit drag racing team. The Cyclone is an X code 3.91 gear, and the Mustang is a Y code 4.30 gear with a 4 speed. My Cyclone was sold through Yorktown Mercury Sales Ltd. in Toronto.
Amazing that these cars have survived all these years!
