I understand that the Mk IV's were Angliss's production and were done quite well. I wouldn't ever call it an original, but it was the closest thing to an original in that era. Angliss had Ford support for these cars and had spent a considerable amount of time restoring them. If I remember correctly, (alway a questionable assumption), he had some ownership connection to AC at that time??
Maybe an expert can correct me on this.
Great car and a good price, but lose the 302 and drop a 427 SO in it to make it better.
Hope this helps.
