Try giving Mike Papworth a call. I imagine he'll have a few knocking around in his workshop. (07768 775170)

Part number 21H5479 for the bolt - but no-one selling them that I've found so far. Have you tried Mike Papworth?

I worry why it broke so might be best to replace all of them, if possible.... Trouble is over the years it appears theres different part numbers but dont know what the differences were...
