Hi Rolf,
auf meiner Teileliste 45.011.0 sind nur der Bügel und die zwei Abdeckungen angegeben. Nix mit Schraube. Die Schraube ist definitiv aus Kunstoff!
60 00 072 156 or 60 00 072 157 (page 40.01 in Renault Spider ersatzteile.pdf)
which seems to be a collection of bolts etc.
I have tried to order one of the above (I have a windscreen-Spider) but my local Renault-dealer didn't recieve the parts from Renault France.
A couple of these bolts have their threads damaged on my Spider too so I'm also interested in finding these.
By the way: In the back of the car there is small rubber-buffers (4-5 millimeters in diameter) sitting between the engine-hood and the bodywork. Some of them is missing on my car and I wonder if anyone knows where to find them? (I suspect thay are part of collection of bolts mentioned above).
