My Nephew has a 1972 Mustang that has not been converted. He uses it to go on Classic American Car rallies. Not a huge problem with the Mustang as it is fairly small.
Performax have got approval to meet ADR regulations for new Ford Pickups. They have modified the Diesel engine, so it now can meet Euro V regs. As well they have replaced items that have had problems in the U.S. and retuned the suspension with updated shock absorbers to improve ride and handling on the Lariat models, also they have added the HEMA system to the standard Ford Sync electronics.
