Tuckwell, eh? That's literally around the corner from me. I haven't seen it. Actually, I'm amazed that there are so many posters here from the Hills area and yet I haven't seen a T18, or Classic Celica or Corona Mk2 zipping around the place.
As far as the 2TG manual goes, I got one and have put it onto CD. PM me if you want a copy. You can actually come around and pick it up seeing your a local Hills lad.
