Mount it brand monitor stand adapter~ model MI-788 vesa adapter

So I bought these monitor stand adapters to try and mount my monitors on a dual monitor stand I got from Amazon but unfortunately when I got the stand, my monitors did not have screws and I completely overlooked whether or not it would need to be having screws so I had to buy these to try and compensate for that the first ones I got I thought would bake me have to still need screws, but then I got them and opened up one of them and it still needed screws so then I boughtthese different ones the day that the first ones arrived and these ones are a little more like what I wanted they grasp around the sides of the monitor now my main thing was I had this but it wasn’t the right size for the monitors I have because it needed to be able to cover a wider distance so then I try to merge these two and make something that would actually work for what I needed. It almost did until my main monitor ended up being too much weight for the monitor stand so I had to send the monitor stand back to Amazon and I had to try and get these returned tomount it which is the company that I bought them from online and I got the refund but they said because the cost of shipping would be too much. They’re just gonna refund me and have that be that and I can do whatever these and I figure I need money I’m gonna try and sell them. Maybe someone out there needs these and will buy them from me It’s worth a shot
