Mavic 851 Mech spare parts

[Old Ned]

I have one of these but the bottom pivot bolt has sheared off in the 'nut' that attaches the body of the mech to the jockey wheel cage. This fits into a slotted hole in the cage for adjustment. Does anyone have a damaged etc. mech that has these parts on it?

I will also need the 'washer' that fits onto the top pivot bolt that has 'ears' that locate onto the stops on the gear hanger. I know this has been mentioned on here recently which is how I realised it's missing!

Thanks in anticipation!
