Finally I found a company that do not think I am mad when I say the distance between the mounting holes on my front struts is 58mm NOT 52mm or 54mm
That company is Koni, the only ones I have found to offer front clio struts with a 58mm gap (only found on 1.2 + 1.4 phase 3 clios made in 1998 apparently)
Anyway they aint exactly the cheapest around at £100 per shock (top adjustable for firmness) but are they worth it?
I have a feeling that this is going to be an inevitable purchase as my shocks have started to leak they are so battered. Still some positive feedback would ease the forthcoming credit card assault
