you can get a generic mk3 clio one off ebay and get someone to cut off and re weld the radiator bracket in the correct position.
The only difference between the normal clio and Rs is the location of this bracket
In the fusbox by the steering wheel, I believe it was the 15A one off to the side by itself. You have to pull the trim off to be able to see it.
If i remember i’ll grab a picture later.
For whatever reason they don't come up for sale particularly often. It's worth keeping an eye out on the facebook pages, I saw this one pop up earlier
