I used Franco at Ricambio for the Italian wings, as he has the Italian ones made in the Rhibo factory, which are really good quality. They are not cheap though, but I had no choice as I couldnt find early Italian ones anywhere else.
If you need a front panel, try contacting Steve on here. He has another two front panels for early 126, one is a fiat original panel from the factory and the other is a quality repro from the rhibo factory. Both are in good condition, I have seen them. He has the panels in Halstead in Essex (closer for you).
I have his contact details if you want them I can PM them.
Franco has Italian front panels also but they are about £90!
