Hi Tony,
Sorry for few days delay in reply. I’m still waiting to do this repair but others have kindly helped me with information. It seems buying the part from Peugeot is cheaper than Fiat, the Peugeot part number is 2344C9 and this part costs between £150.00 and £200.00. Fiat wanted over £250.00.
The best place from all the advice I’ve been given to do the job is Transmission Services in Guildford who put labour at between two and three hours. They have done this job many times before and slightly overfill the gearbox when replacing the part. Apparently you don’t also need to buy the synchro and this part can be reversed. You will find huge variations in quotes so if you plan on repair in Europe make them aware you know what is involved so they don’t try and overcharge on labour or buy extra parts you don’t need.
Good luck.
