Don't make the same mistake I did,I tell you now I was in such a situation.
Not only was I one of the very few with 54mm spacing or 52mm i forgot which evers rarer anyway, a big fat greek bloke at a garage who I slipped £20 to broke the hub.
"Sorry I broke your hub"... well seeing as you have a big fat breakers bar in your hand and your twice the size of me, thats alright in fact i was going to do that myself......
To save the agro of sourcing another hub I went down the scrappies and brought front supension and hubs, see there was 5 clios down there all had the same hubs (The one that dont fit mine, so i just changed the supensions).
The moral of the story? buy a second hand hub for £20.
