I used Pelican cases on my 2016 Moto Guzzi 7II. Photos below:
Fender washers may not have been necessary inside the case, but I like robust.

I taped the bracket for 5 mm bolts, then added locking nuts to the back side. May not have been necessary.

That is pretty cool! I have Givi monokey mount plates on all of my bikes, and I have always wanted to figure out a way to fabricate a "box-end" hardware setup to be able to securely mount any box I want. In particular, I'd want to attach the hardware to an old-school aluminum briefcase, which would be a good vintage look for any of my bikes. If you have any ideas for me, I'm all ears...
