I don't see why something like the PP-mount/mold for Connext boats manufactured by JetBoatPilot wouldn't work for a standard (round) display Ridesteady gauge.
The back of the "external display" (the one I have) is just flat with a cable coming out in the corner, I will try to find a pic.
At least for now, mine is mounted using a RAM plate and VHB tape provided, the other RAM plate is attached with VHB to the edge of the dash insert. I let it cure overnight and was surprised it held up to my rides, so far.
EDIT:
@Mainah I was able to sneak the cable to the external display and GPS antenna in between the dash parts, without cutting ANY holes or grinding anything. I think I may actually leave it in that location as it is very easy to reach, may just need to better support it w/ either screws or epoxy.

EDIT 2: Here is the Jetboatpilot's PerfectPass housing, he offers for PP on his site but should work with any standard gauge.
