use a socket A h/s on socket 478?

[player]

Is there anyway to mount my big chunky socket A cooler on my P4 board? I have a great heatsink lying around but need a method to clip it on. Any plastic mounts which I can buy that act as the retention mechanism like on the socket A boards?

It's a thermalright copper one, with, what I think is just a standard clip retention thingie me bob!

edit, think the model was the SP-70 or something similar.
