Heatsinks

Hi

Does anyone know where i can get a heatsink for a TDA 1521 philips amplifier IC? The IC has two nothes, one either side. I have attached a picture to demonstrate. Thanks for any help

My guess is that any heatsink will do and it's the method of fixing that is the issue. What about a small strip of brass secured by a screw at either end?

this is what I made for the LM4780 which has a similar hole arrangement -- adjust the dimensions for your purpose -- it snugs the chip up to the heatsink quite well:
