Roo Lite Mounting Bracket

Can anybody suggest where I may be able to buy a replacement bracket for a Roo Lite. I broke the mounting bracket on my son's car the other day, and a spin around the (fairly useless) spare parts shops, and Google have not yielded me any results.

I think I may need to track down the supplier to get one, but not having the packaging etc I can't track them down. Everybody 'knows nothing'.

Thanks in advance.
