This may prove valuable for those who do not use the standard diff rebuild kit (as the regular kit has the ring but the ceramic thrust kit does not). The xray diff c-clips are the same as the corally c-clips. They are sold seperately and come in a set of like 10 for $5.75

Got to be one of the most reasonable prices xray has for a part.
