I too liked the jdm badge more.. I myself have done the outside badges, the center caps, illuminated kick plates as well as a nissan key fob. I have a contact in Australia who said to order the airbag and engine cover from a nissan dealer in Australia or find a nissan car owner and swap with them. The skyline owners wanna trade to G37 badges as we wanna trade to Skyline badges. The car matts in my car are the rubber matts so that infiniti logo is long gone. My friend owns Nissan Unlimited located here in houston tx. He sells used parts for nissan and Infiniti cars. I got the center caps from him for $40 for the set in mint condition.
Hope this helps...

 

If i go to japan in the summer time i will pick one up. It will not be cheap because you have to buy the airbag w/ it. If your down, let me know. I will try to figure it out the price soon and ask my friend.

 

where in houston exactly bc i stay in houston to and im looking for the center caps also
