OK - finally the answer to the original question...

I measured the OEM collar - or at least the one that came in my 2008 Zuma that I've owned for a bit more than a month...

And, it's about 18mm.

I also measured the hole in the OEM and NCY variators and they're also about 18mm.

I just recently bought that super tranny kit...

Maybe your 20mm collar is a 2001-2007 thing. I read that Zuma things changed in 2008 with throttle cam restriction, gearing change, etc. Maybe they also changed the variator specs?

here are some photos:

Awesome, thanks Jack! I think the issue is that the variator and collar that was in there was not actually stock. Someone must have replaced it with and AM one that had the 20mm dimension. So to use the NCY, I would have to locate a stock collar.

Thanks for all of your immense help Jack!
