Hi, Mutt,
I don't know about a website, but I had an '81 280ZX when I lived in Culver City, and there was a shop in Venice called Z Expert (or maybe Experts) that was one of the best places for both service and info on Z cars that I ever found. That was about 10 years ago, but I think they should still be in business and should be listed in the L. A. west side phone book, or by now you should be able to find them with a search engine. I'm at work now, or I could give you the phone number that I have for them. I'll check on this and give you an update in a day or so.
