Try this site great for part numbers.
Www.catcar.info/en/Doesn't work off reg number but you will need your model type and in some cases fabrication number.
Model type = look at oval plate top line left mine is a cc so it's a EZ1S you will need this model type.
Fabrication number now can't find a lot on this but I believe it's again oval plate top line right side seems to be a letter and a set of numbers and I think it's the number you take note of. Anyone want,s to put me straight please feel free.
It's a good site once you get the hang of it
I worked out the number for my front spring, wrote it down then orderd one from renault via reg number, when it turned up i checked the part number with mine and it was right so I feel it's a good resource once you work it out on the plus side at least you have the left hand shaft number so it should be simple to match the fitment into for the right one.
Hope this helps
