That'll do it. I might even be able to knick the gopro mount bit and fit it to my existing garmin mounts? Problem with the one that came with blubuzz mounts is the tabs are too wide and don't fit into the apeman case. There's also no bolt there, even if they did fit.
I have been using one of these for a few years now, fits any go pro looking knock offs and indeed a go pro.

Just go through a couple of pages on eBay, might cost me like £6 or something.
