Yeah searched earlier and found your thread with the ebay link which made me start this post
It said they were for Fiat 500 but at the same time also said "These are standard replacement windscreen wipers only for models fitted with Aerotwin wipers from new (factory fitted)" and not to order if not.
I took a wiper off today and its Fiat branded which is where the confusion lies if they'll fit or not?! Mines a 59 plate so i'm guessing it wont be a straight swap.
I've also checked out other online stores and most just show the rear wiper only for the Bosch with many showing as none available.
