This list will grow with time. Many people that are involved with Patrols are also fans of other Datsuns. Over the years I have met many great people in the Datsun community; we are a very loyal bunch. I will never forget the very first Japanese Classic Car Show in 2005: the event was put together by Toyota clubs mainly and they allowed People's Choice voting on the cars. Well, the Datsun's totally walked away with most of the awards, even though there was a strong showing from all Japanese makes. Since then the organizers of the event do the judging themselves. Anyway, this list of links is for Datsun clubs, organizations and historical sites.
