My New 72z
For an eclectic, sometimes strange group of serious datsun heads I go to this site:
http://forum.ratsun.net/index.php
There are a ton of Z only sites. I kinda like Ratsun though, because it is kinda low-buck and definately not dull.
I lean towards the 510's myself, but they are real hard to find anymore.
Nice car, and good luck. They are fun.
