Forget Italy for X1/9 stuff, Daz.....!
I totally agree with Todd on this matter, mate!!
In mid-2000, (not very long after I had bought my X1/9) a friend and I were touring thru France, Italy, and Belgium.
I (innocently) thought it would be a great opportunity to pick up some X1/9 parts/info that were not available in NZ.
We were staying in Ostia - not too far out of Rome - and when driving into Rome soon after arriving, I spotted a
LARGE Fiat dealership on the main road heading into Rome.
I went in to the Parts Dept to enquire about X1/9 parts availability, only to be met with a puzzled look from the parts counter guy who opened up a huge All-model Fiat Parts catalogue, shook his head, and said "X1/9 not Fiat model, maybe you try Alfa or Lancia dealer!"
With that response, I gave up looking in Europe for X1/9 parts!
(I didn't know Paul in the Netherlands back in those days.)
So, best of luck in your search, buddy!!
