Where to find and how to replace the infrared led array in the ring?

So whenever I was fixing a stuck button on my left controller i managed to tear one of the it sensors off on one side of the ring, just one. Now only the other half of the ring works. I tested this with my phone camera. I would like to know if anyone who comes by this post knows of any place that I could get a replacement infrared led set. Or replacement parts in general for the rift s controllers. I would buy a whole new controller but I don’t have very much trust for oem resellers. Unless anyone knows of a reputable reseller.
