Rear brake back plates

Rear brake backing plates
Evening all I have a corrosion issue with my wife K 12 1.6 c c. My question is as most of the suspension and brakes are a Clio set up, does anyone know if the Clio back plates fit? They look very similar but have some subtle differences but not a lot it’s hard to say looking at eBay pics. The main one I can see is that there is an inspection hole on the Clio ones where as on the Nissan there is not .
