Wanted Gates G63120-1206 12mm - 6FP Thread adapter

[caffeine]

I'm looking for a thread adapter for installing an older 3/8" NPT CTS into the 3.5L CTS stock location. I'm aware that carquest can get these but there aren't any shops around where I live that can order this and the cheapest place on-line would have come to over $50 with shipping.

If you have one or can get one for me, how much shipped to V0R 1N1 Canada?
