I'm not sure what you want to achieve... are you specifically looking for those wheels for a Mk1 car, or did you just see them and like them?
They look like the most obscure Fiat alloys that it is possible to get for those cars so I'd say you have no chance of finding them. There were some other 6-spoke 14" rims available for those cars (I got some from ebay last year, scruffy but good price) and a few 5 or 7 spoke 15" alloys - these do generally look better but if you're going for the Mk1 look then almost any Fiat 14" alloy should do - Punto, Tipo, Tempra, Marea, ....
