Where to Purchase Heatsink Clamp

Hi guys, I went ahead and cleaned my PS4 Pro the other day, which I bought used, and discovered that the x clamp that binds the heatsink to the APU had been replaced with a standard PS4 clamp, that only has two screws. Obviously, this isn’t ideal for heat dissipation, since pressure is not applied evenly all across the die. I would like to replace it, but can’t find a place to purchase a proper replacement clamp. Does anybody have a source?

eBay is really your best bet here. I don’t know of anywhere to find them other than that but there may be somewhere out there.
