I will be driving from Munich to Llubljana via Austria and Italy probably going near Trieste, Udine or Tarvisio.

Where should I look to purchase a Wind Data sim? What type of shop will carry it?

I already have a codice fiscale.

Thanks, Jim

You don't need a "data sim" just a normal Wind prepaid card. If you'll be in Trieste look for one of the 2 MondoWind shops:
VIA CESARE BATTISTI, 20 - TEL 040/367950
VIA MAZZINI,45 - TEL 040/3480694

Maybe our friend Triband81 knows where they are since he often goes there! :)

Thanks!
