In the process of putting a scooby diff in my spitfire.
this uses the scooby inner CV's (mated to metro shafts and outer cv's, all slots together nicely)

However, my CV's are missing the snap rings. And not obvious where to get replacements. Scooby dealer not close and even less helpful.

Do i measure the splined part of the shaft and the groove size? And then get generic rings? Any idea on suppliers??

Cheers
Clive
