Maybe not...
But it might be a new idea to the people that don't know the unabridged history of Datsun, aren't mechanics, or haven't been into Z cars / lived on the Z forums for 5 years. I certainly haven't seen a sticky talking about it at all, so I think bringing something like this back up is a fine idea until there is a sticky or reference mentioning such a thing. How would a new person know about this otherwise... certainly not by searching... if they didn't know it existed to search for to begin with.
