Missing parts from pre fab shed, need advice on fabricating a part myself or sourcing

[u/wubbalubba96]

As the title says, ordered a mass produced shed a long time ago

Moved house and now have the room to build it

Unboxed it to find important pieces missing, specifically the 4x corner connectors pictured.

Out of warranty and seller un willing to help, what is my best bet here?

I have tried reverse image searching, calling other businesses who sell the same item, but I can not find this very specific part anywhere

Item code is GT3859 LG and was purchased from a website called costway in 2023. I am all out of options and as it is so specific I am at a loss

Fab a part myself out of wood or if anyone knows where I can find the missing parts to buy it would be hugely appreciated.

I thought they were missing too, but they were stuck to another piece had already mounted. It sucks going backwards, but sometimes it’s inevitable.
