But from your earlier arguement Darin, it would have to be listed on the spec line of the car to be legal. And, while I'll have to research this, I don't think that it's a requirement that legal parts be available from the factory.

But as far as your scenario w/ the new part #, I would still think you'd need something in writing from Datsun/Nissan to the effect that this is the new part # and the old part # is NLA, possibly w/ the specs of the new part.
Bill... You are correct, and based on our current rules, none of this has ever been in question with me. What we were trying to establish with the last set of posts what WHAT constituted a part that was eligible to be listed on the spec line... or, in other words, WHAT qualifies as a "supersede" or "replacement" piece...

The only document required by the ITCS is a "manufacturers parts guide", which would generally show the old part numbers and the new, and in some way indicate the availability.
