Missing xclamp mounting xbox series x

Purchased a broken xbox series x, wanted to try and fix it. Powered on then turns off. Booted to safe mode with no hdmi signal and fan ramps up. While taking apart I found that the xclamp is missing. I figure APU isn't making sufficient contact with the heat sink, causing the system to shut off. Anyone know where to get a replacement xclamp? Looking on ebay currently with no luck
