Its #877 in the diagram. mopar #4207265 and just doing a quick search on my favorite dealer site its being called out as discontinued. Is there an aftermarket listing for this one ? I found the listings for the front snap rings (#876) and the snap ring thats used in the front drum (#878) but not this one . I believe I damaged mine during a mockup install
