IIRC the banham moulds are reproductions of the original ford moulds as banham bought the ford mould then had them rebuilt and repaired as they were not in best condition. They used to provide the body parts both for their maestro based cars and the genuine rs200's.
Did spd get those exact moulds????
would be interesting if someone like RS automotive had the funding to re-engineer thier design to the correct wheelbase and use the dimensionally accurate panels. would be awesome then.
