IIRC, those look to be rear brake pin retainers, used at the pivot for the 
parking brake lever / arm, under the�drum, at the actual brake shoe. Can be 
re-used in a pinch, but should be changed every rear shoe change.

Subject: Unidentified part

Can anyone identify the part shown in the link below?� I am referring to the
flat circlip/alignment-shim-looking parts to the left of the cotter pins.� It
came with a box of late model old stock parts I just bought.
