I FOUND WHAT I WAS LOOKING FOR. Thanks for those who've read this to see if you could help.
I am looking for the metal brackets that screw on to the bottom of a Mugen 2 heatsink and allow it to mount on a 478 board.
Does anyone have extras from your Mugen 2 you'd be willing to sell or just let me pay the shipping costs?
I bought a used heatsink and was promised the brackets were part of the deal. Didn't get to the project soon enough to notice they were missing and lost my window to make the return.
A picture of the brackets are shown in this pdf of the mounting instructions. ftp://ftp.scythe-eu.com/Manuals/CPU-Cooler/Mugen-2.pdf
They are shown in the picture below on the left side, underneath the black backplate and above the fan clips.
