Need Help Please, 20" Ultra Motorsports Clip-in Center Cap

I have a 2017 Tundra that came brand new with a set of 20" matte black Ultra Motorsports wheels on it. I've recently lost a center cap and have been trying to find one. I just received one that I bought on Amazon just to find out that it's a bolt on version. The one I need uses a retainer clip on the back of it. I've pulled one off the other wheels to take pictures for you all. I've searched all the numbers I found on it with no luck. I'm sure someone else has ran into the issue that can give me some advice on how to handle this. Any help is greatly appreciated.

 

Have you contacted the manufacturer? Wheels/centercaps may or may not still be available - that shit changes everyday.
