Did you get any further info from Alfa on this? I'm trying to order one for my car.
Edit: MacGeek has kindly confirmed that 50535783 is the correct part number for the Italian market front plinth. For future reference he has also advised that the part number for the smaller Italian plinth for the upcoming Stelvio Quadrifoglio is 50552824 in case any potential buyers of that version also want to fit a smaller front plate.
