I mounted the shroud to the radiator using high temperature bolts and lock washers.
BTW, for those of you trying to cool down you C3 while driving on the highway I finally found a place selling the Front Spoiler (Air Dam) extension... I searched for a few hours for this after seeing a fellow C3 owner that had one installed. He said that they weren't made anymore, glad I found out otherwise...
I have the same setup as Bacalou. The shroud is mounted to the upper and lower rails of the raditor with 4 small bolts and nuts. The holes in the shroud were predrilled on mine, but the holes in the radiator rails were not. It was easy to do and looks really good all bolted together.
