So it is. I was in a bit of a rush when I posted, didn't see that bit of detail.
That's really strange. Can you get some pictures? From what I've read, there's no series 1 cars with series 2 bits on them, it's either a series 1 or it isn't. As for the trans tunnel, as far as I know, all 240Z trans tunnels are the same, except for the shifter opening.
