So I recently got a 57 plate YBR125 from my ex. He damaged the clocks back last year and refuses to give me the replacement brackets. I managed to get a set of the outer casing from ebay but whilst I started to put them on I realised hes also broken the two circular things with the glass (well plastic) in. Is there anywhere I can get just the clock plastic covering without buying the whole clocks bit? If no one understands me I'm sorry.
