Finding a spare set of Sachs these days will almost be a matter of luck. Your best bet is to buy a pair of cup dampers to fit whist the Sachs are off, someone is actually more likely to have these and want to sell. You can then move them on after.
You can pick these up from Renault parts direct though like everything these days, not as cheap as they once were.
