A833 Rear 207 bearing

Alright I am back at it again with the a833 questions... So I'm reassembling the transmission with the new 66-67 tail housing I bought to adapt to the slip yoke and this specific year of tailshaft requires a 207 bearing for the rear (6207 N/C3) and I can't seem to find a snap ring with the wierd prongs on the end anywhere. Does anyone know where to find a snap ring? Passon and Brewers don't seem to have them.

Also does the 207 bearing have to have the groove in the bearing for the snap ring or will the snap ring go in front of the bearing
Thanks.

207 versus the 308 for comparison
