CV Axle Snap Ring size? How do I know which to buy?

[Chibu]

Sorry if this has been covered elsewhere, I am quite a noob at searching on this site. I figured that there isn't (or hopefully there shouldn't be) a "guess, check, and revise," method for figuring out which snap ring fits on a CV Axle. The time has come to replace the CV Axle with a new OEM one and the seller says the Axle won't come with a clip. I looked on a Lexus parts Catalog (toyodiy.com) and it lists a host of C-clips (snap rings) ranging from T=2.8 to T=1.8 (in what I believe to be millimeters inches). So what I want to know is, how the F do I know which clip to buy? Do I measure the diameter of the axle at the end where it comes out the hub? Or....?

P.S. Is T=2.8 to T=1.8 the thickness of the rings or the internal or external diameter? Istg we need a dummies manual
Okay, so I figured that T=2.8 to 1.8 is the thickness of the rings in millimeters and it depends on the gap between the snap ring and the mouth of the flange.

You just get two of each and see which fits when you get to that point. Then throw the rest in your spare parts bin.

Here's a kit that has what you need:
