MBD200 Query

Does anyone know if you can buy parts for an MBD200. I have a cracked section around the AF-ON Section. This was caused by a break in the strap of my Loewepro Nova 2AW bag, its done good service for 3 years but the catch broke, the bag fell and you can see the result in the image below. It is still working OK but I would like to know if it is fixable. Anyone had similar problems and fixed this?
