Heatsink Bracket and Clips for new CPU cooler

This Zalman is too loud:



Here is the funky bracket the Zalman uses:



Here are the two mount points, one with the bracket intact and one with just the standoff:



Here is the Zalman cooler and clip:



The new coolers have standard square-hole clips:



I inherited this motherboard/cpu/cooler combo from a friend, so I do not have the original mounting parts. I need a new bracket to attach to the motherboard that will accept a standard heatsink clip. I have not been able to find these parts on the Net.

Update: What I needed was a plastic Socket 754/939/940 Heatsink Retention Bracket... just like this one I received from a local Linux user:



I had to partially remove my motherboard from the case in order to install the backplate. Here is the new bracket installed:



And here is the new AMD heatsink installed:



The new heatsink actually came with another CPU (AMD Phenom II X4 940 Black Edition that I installed in my HTPC). After replacing the CPU cooler on my desktop CPU pictured above (AMD Athlon 64 X2 4400+), I discovered that the fan in my desktop with the most annoying pitch is actually on the video card. However, I am still happy that I completed the project because overall the system is quieter than it was before.
