Clips for Blizzard PPC

This is my first post here even if I have been reading the site without getting an account here.

I have been asking around in almost every forums at Internet and now I will try my luck here.

I?m looking for that clip who hold the black heat sinker.
I have one but it is hold by two.
Have asked the Amiga Center in France and he didn?t got any spare parts.

I had got some tips to use anything else like fans and heat sink from a graphic card and I can do but I would still like to have that black original piece in place.

Hope there is anyone out there to know where to found this small part.
