Hey Jim looks like this is the kit for the green bearing with the snap ring, don't know how quick you can get it though. I've bought a few of these kits from a guy on ebay named Mopar Madness, with good luck, although this is not one of his kits.

This uses the green bearing , ST-400 (Snap ring ). The outer race on the bearing has a groove and spiral lock arrangement that butts up against the outside edge of the brake backing plate and is also good for disc brakes if you ever convert.
