Need 2 back boxes for Bosch Model: NTI-50022-A3S Dinion IP Bullet 5000 HD CCTV Cameras

I have two brand new Bosch Model: NTI-50022-A3S Dinion IP Bullet 5000 HD CCTV cameras that I bought on ebay, however both are missing the back boxes. 

The seller doesn't have them, and I reached out to Bosch and the only back box they have that their system says should fit this camera is too small.  

I figured it is worth asking if anyone has any laying around ( maybe you uninstalled these someplace and threw them in a pile in the garage?). If you do, please reach out to me - I'd love to buy 2 back boxes for this camera.

Thanks!
