A Clean Little 69 Cent Mod.

No, I dont have a part number, which is one of the reasons I posted a picture of the part. They are in the fastener aisle, in one of those pull out drawer specialty part
boxes, divided inside by size. The one you want is fits hole size 11/16". People frequently take a part out, but then put it back in the wrong size section in the box, so just take a 17mm socket with you to make certain you are getting the right one. They are a little tricky to remove without damaging them, but at 69 cents each, having one or two spares for the infrequent need to remove is no big deal.
