i think i know what your on about, i think i have 2 of these but there off a phase 1 bumper but they may fit a phase 2 bumper, as a phase 2 bumper fits a phase 1
They wont fit a 172, as the 172 as wider arches and track the front wheel arch has a wider bit on it. Which side do you need, they are quite pricey from Renault.

Yeah, they are expensive from renault, I can give you the part numbers or you can try some scrap yards or anyone breaking a 172/182. Youll mostly need the drivers side as the front part of the wheel arch also protects the aux belt and roller from the elements.
