How much was it for you to get yours? Were both in NorTex, should be about the same for me.I had to order mine from japanparts. It actually worked out pretty good, no problems at all.
I don't know if you will find these in the US, they come standard JDM and European R18s.
Do get the new valve cover bolts, it will keep it from flopping under the hood, and make it look like it was factory installed.
