Thanks Quentin, I measured mine yesterday and found I have the Orig Cobra Mota-lita pattern of 62MM from the 1 o'clock to 7 o'clock position.
Funny I can now see the top two screw holes are further apart than the bottom two. Making the pattern asymmetric. I'm a little slow on the uptake some days...

So the NRG adapter is def off for a bit until I decide if I want to get a different wheel as well.
