If you ruined any Intel Socket 775 push pins, like I did, you can get them cheap here:
https://www.industryeducation.com/Desktop_Heatsink-Kit_Fasteners_for_LGA775_fan_heatsinks__set_of_4_-P5904.aspx
This is a store that sells internationally spare parts for Intel, such as original heatsinks, socket covers, brackets, etc.

I hope this saves somebody from trashing their heatsink for bad push pins.
You can replace those loose pins also.
