By the way, I should clarify, the two cars Dick Johnson purchased from Zakspeed in late 1984, were not built by Zakspeed specifically for Johnson. They were existing race cars by my understanding. However, I don't know if they were cars Zakspeed had been racing themselves, or cars Zakspeed had built for a customer in Europe. There were a lot of championships taking place throughout Europe for Group A cars, and several Mustangs were racing in these, so its possible Zakspeed were running the cars themselves somewhere.

One book I have says the cars were originally built in 1981 and 1982. But Group A wasn't introduced until 1982, so perhaps the first date is incorrect?

Can anyone shed any light on this?
