If I remember right,the Thames trader came with a 1500 cc crossflow engine,I think that only the earliest cortina mk1's came with 1500cc, after that it was 1300 or 1600cc, anglias also had s/order 1500s for race/rally.I'm going back to my days of youth here so I might be wrong on some of this.I would go on line and try to find the parts in the U.K. exchange rates arent all that bad and parts are away more plentiful.
