Earl is correct you need for 66-67 Chevelle not GTO Lemans. Original parts Group in California has them and do International shipping. Payment by Credit card or Cashiers cheque in US funds. They have 18 GA or the cheaper 20 GA. If we did it for you we would have to order it the same way. No advantage that I can see. I think the shipping of this part will be more than the cost of the part itself to your country. But if you need it you need it.
The 18 GA is around $119.00 U.S. and the 20 GA is around $86 U.S.
