Sorry I didn't make that too clear! I have quite a few fronts but have nearly run out of the rears so can only do a few more complete sets.
I do have a couple of extra rears but the Renault part numbers aren't printed quite right the line that says "do not open" has dropped over the background...
Some of you may have seen these on eBay as I thought I'd test them out there first but then just never got round to putting them on the forum.
For sale are genuine replacement Sachs Damper stickers.
They have the correct Clio Trophy part numbers on them and are printed on the newer ZF group...
I spoke to a company called Firstline who make these for other cars, The nearest one in size to the Sachs one is for the rears on a Ford Mondeo their part no. FPK7059 it has a similar length and bore! and could possibly be modified to fit! might be worth a try.
