Hey guys, I moved to another apartment a few months ago and unfortunately one mounting bracket was missing. I have spent the past 3 days searching the internet for a replacement pair without luck. I found in China but shipping cost is very expensive ($70) and I will probably hav to pay customs. So, I was thinking maybe it is cheaper to buy it from Amazon if I can find it there maybe.
Can anyone please tell me where to find it?
Thanks!

This is the one I have. The other one is lost.

I found these on Alibaba.com but I can’t buy them because shipping cost is very expensive and must buy in bulk.
