I agree with other posts - this is not TI Super, which is flat to go in front of rad, TZ is very similar to yours but, fastenings and pipe position different. So I agree GTA, don't know GTam well enough to comment.
The fastenings/pipe connections have been altered significantly; my reference books not to hand, but can check on Monday.
PS Interesting to mention Piero Pizzaro - a name from the past! - used to visit his shop frequently!
