Hi all I have a 2003 fabia 1.9 tdi I need a new strut can I hell find one is there any other vehicle ie vw or skoda that use the same strut that I could use 

not sure why you can't find ONE?   but SEAT ibiza or polo should do but will need to be fitted as a pair as the damping will be different (even)between 1.9 diesel models  without  going to all the others ie: (petrol ) etc

Can't use the petrol one's and there aren't any 1.9 diesels anywhere 

Why do you need the entire strut? Springs and dampers are cheap enough if either one them has failed, but as already stated you should really replace them as a pair.
