Freakin' Horseshoe clip!!

I have always re-used the C-clips because, as you say, "not in the bag". You can buy them separate. The steel seems malleable and I never had trouble squeezing them on, but I don't recall a "wave washer" so maybe that gave me more clearance on the groove. My 1965 has 10" brakes. I should look close at the FSM parts or maybe they added that later.
