Where can I find this c-clip?

I need the c-clip that sits on the edge of the outer cv shaft, an hold the cv shaft into the outer cv joint. The shaft is then pounded into the outer cv joint. Toyota does not have it. They only sell the entire shaft and joint assembly. Local napa had nothing. Must be replaced when you take the shaft out of the outer joint. It is a round edge c-clip, or circlip.

Looks like this:


Any ideas? Or a part number?

 

Fastenal or a similar store...take the old one with you to compare with, tell the guy at the store what your intended purpose of the part is
