Push Pins to mount things to motherboard

I need some help. I have an IWill KK266 motherboard. It has given me lots of trouble lately (another story). I am getting ready to send it back to where I received it, but here is my situation. I took the passive heatsink off the motherboard northbridge chip and replaced it with a Blue Orb. When I did so, I was not able to save the push pins which attached the passive heatsink to the motherboard. Now that I need to send the motherboard back, I need a couple of the plastic push pins so I can reattach the passive heat sink. I have called several of the local computer shops and no one seems to know where I can get them.

Do any of you out there know where I can get some of these fasteners? I need an answer quickly as my RMA number will only last a short time. Thanks ahead of time for the assistance.
