Where to Buy Abarth - type wheel arches, GRP Bonnet & Bootlid ?

Hello, I'm from the UK, I'm in the process of buying a really nice '77 Spider which I'm going to convert into an  Abarth Replica, with Cromodora CD 30 or CD66 wheels, GRP Bonnet & Bootlid, & either the narrow or Gp 4 flared wheelarches.

At the moment, I can only find a supplier In the USA that lists the wheelarches..

Are there any 124 spider parts suppliers in Europe that sells them please?

Would be appreciative of your help!
