How to attach a GoPro to a Nauticam M10 ball

[TampaDiver68]

Leaving for a trip in 4 days, and my wife has retired her GoPro 7- I figured it should be easy to attach to an extra M10 ball I have on my Nauticam housing to play around with. But in researching, I can't find an easy way to do it. Any suggestions? I have a few LOCLINE flex arms with YS mounts, but I don't this these will be useful.
The GoPro as a housing, but no clamp to connect it to anything - she repurposed the original it for her new GoPro.

…or perhaps remove the M10 ball and attach the locline base to the Nauticam housing…. But the bolt is too big (diameter).

But how to attach the locline to the gopro

What's wrong with a GoPro ball mount? Just use that and a clamp between two balls.

Man... I guess I really was overthinking this one. Figured I needed to get the GoPro up a bit higher, but is seems like the length of a standard clamp would do just fine.

I decided to go with this:

Hate to pay 10x more, but I need it overnight.

Thanks for showing me the light!
