Need Help Finding a Deepcool Castle AM4 Bracket

I am gifting my Deepcool Castle 240ex AIO to a friend. I just realized that his build uses an AM4 sock, while uses is a LGA1700 socket. Mine was a prebuilt from Cyber Power so they didn’t send me all the extras that come with the all the components, like the AM4 bracket. I can’t find any on eBay, Amazon, or Facebook Marketplace for a decent price. The whole idea was to gift him my current AIO, so I could have an excuse upgrade to a Corsair one to match my system. At this point it would cost the same to just to get a new AIO or air cooler. Either way, I promised him (my nephew) I’d give him my AIO, so I have to get him something! I convinced him to go PC, and I would help him build the machine and I gifted him a few items already.
