Thrust bearing sizes?

[CODMAN]

Guys, I've got some carbide 5/64 thrust bearings laying around that I want to swap out in my B-max4 diffs. I read in one of the posts here that the original are 2mm (metric). 2mm is about right, but still almost 1% off... Am I splitting hairs here? Will these bearings be OK in the diff? Or should I find some metric 2mm balls instead for them? I know tolerances on these bearings are tight, so I'm a bit worried about not putting exactly the same thing back in...

Any feedback to calm my nerves would be welcome!

Thanks!
