Need replacement P4 rentention mechanism! :-(

This is urgent. Does anyone know where I can get a replacement retention mechanism for the pentium 4 -478. It is the part that screws on the top side of the motherboard. One of the 4 corners that locks the clip broke.

You might be faster (and cooler) with some Swiftech unit for example, AVC Sunflower is good too.
