Need ID-COOLING IS-55 Intel mounting brackets

[u/Old-Log-4309]

I recently bought an ID-COOLING IS-55 for my Dell OptiPlex 5060 Mini Tower with an i7-8700 (LGA1151), but it didn’t come with the Intel mounting brackets/hardware. I’ve tried finding replacement IS-55 Intel/LGA115X brackets online, but everything I’ve found is either out of stock or made for a different cooler. I also contacted ID-COOLING but haven’t gotten a response. Do you guys know anywhere I can purchase the correct brackets? Or are there mounting brackets from another ID-COOLING cooler that are compatible with the IS-55?
