Can anyone please tell me which ones I need for the original Stilo alloys? My son got claws so is using the ones that came with the car for those. Now we have a 1.2 (for other son) that came with steel wheels, we have put the old Fiat alloys on it but dont have any locking nuts. I have looked on ebay and some seem to be unsuitable for Fiat wheels and only good for aftermarket ones. Any advice? Also if anyone has a set they dont need please let me know
