OK Mattster, I've had a rake I don't have the exact part but I do have one that fits the bung & allows the bolt to pass though. It sits a little proud at the top but thats nowt a good barstard file wont sort out...
Its about 1mm too tall ! Also the base is smaller but I tried it on my bike & apart from the height it works ok.
PM me an addy & I'll send it up to you.
