Hyper 212x tool kit Problem

[Rumman]

Today I brought a Hyper 212x for my AM4 socket from a person. As I am going to install the standoff screws to my AM4 back plate, I found that those are not supported. (I tried the all other types included in the box.) After researching on internet got an idea that those are old AM4 supported standoff. 

 

Now I am wondering, would I be able to buy a new separate tool kit box for hyper 212x? I live in Bangladesh. If I could manage to find any supported center of Cooler master, will they provide me the tool kit box? (I don't have any paper as the person from whom I brought has lost it.) Or can I find the box at aliexpress? 

 

 

What should I do? Any suggestion??

You can buy AM4 mounting kit separately, yes. Same one that is used by EVO works.
